Ask Deep Research AI: "Please Write a Narrative Descendants Report for Martin Carringer (1758-1835) of Pennsylvania"

 Earlier this week, I requested the freely available ChatGPT4, Google Gemini 2.0 Flash, and Grok 3 to tell me "Please Describe Genealogy Projects That Can Be Performed by AI Deep Research."  Note that I didn't ask it to do "Deep Research," but only to identify projects that could use "Deep Research" to complete.  

All three AI tools provided a good list of possible projects, and I want to start testing out "Deep Research" on some of the projects.  However, I only have free access so it may not be the "latest and greatest" when I use it.  I can use a limited number of "Deep Research" queries each week on ChatGPT, Gemini and Grok (Gemini told me I had one more free use in the next five days).

1)  I know that "Deep Research" at present can access (some? most? all?) Internet websites and pre-trained textual material.  However, it cannot search in databases (such as Ancestry, MyHeritage, FamilySearch, etc.) that are free or behind a paywall.  Apparently, it does not search within book repositories like Internet Archive or Family Search Books.  Those capabilities are key to effective genealogy research at this time.

One of my uses of Artificial Intelligence on a semi-regular basis is to see what it can find about one of my ancestors.  Today, I want to test if Gemini "Deep Research" can write a descendants report for an ancestor for whom I know the information is on the Internet, and judge the quality of the result as of this date.

2)  I used this prompt suggested by Grok 3 in Google Gemini's 2.0 Flash "Deep Research" AI tool:  "Please write a narrative descendants report for Martin Carringer (1758-1835) of Pennsylvania covering four generations of descendants, including parents names, sibling names, children names, spouse names, and birth date/place, marriage date/place and death date/place information."

3)  Here is the Gemini "Deep Research" Result (after many deep thoughts):

A Narrative Report on the Descendants of Martin Carringer (1758-1835) of Pennsylvania

Martin Carringer, a figure of historical significance in early America, was born circa 1758 and died in 1835 in Pennsylvania. His life intersected with the pivotal events of the nation's founding, as evidenced by his service as a Private in the 8th Pennsylvania Regiment during the American Revolutionary War. This contribution has earned him the designation of a DAR Patriot Ancestor , a testament to his role in securing American independence. Following his military service, Martin Carringer transitioned to the life of a pioneer, settling in Mercer County, Pennsylvania, around 1796. This report aims to meticulously trace the genealogical path of Martin Carringer through four generations of his descendants, documenting their lives and vital statistics as available in public records. This exploration will encompass their full names, parentage, siblings, spouses, and children, along with their birth dates and places, marriage dates and places, and death dates and places, providing a comprehensive narrative of his enduring legacy.  

The early life of Martin Carringer remains somewhat shrouded in the mists of time, as the names of his parents are currently unknown based on the provided historical records. However, his surname and historical accounts suggest a likely German heritage , hinting at potential ancestral roots in the German-speaking regions of Europe. Similarly, the available information does not definitively identify any siblings of Martin Carringer. In contrast, the details surrounding his marriage are more readily accessible. Martin Carringer married Mary Magdalena (Hoax) Carringer in May 1785 in Westmoreland, Pennsylvania, United States. Mary Magdalena was born approximately in 1768 in Maryland, United States , and she lived a long life, passing away on August 31, 1850, in Sandy Creek, Mercer, Pennsylvania, United States. Following her death, she was buried in Perry, Mercer, Pennsylvania, United States. She was also known by the familiar name "Molly". After Martin's passing, Mary Magdalena applied for a Revolutionary War pension in 1839, residing in Sandy Creek township at the age of 71 , further solidifying her connection to his patriotic service. The uncertainty surrounding Martin's early family life, juxtaposed with the clearer details of his marriage and later years, illustrates a common pattern in genealogical research where records pertaining to later life events, particularly those involving family formation and community involvement, tend to be more prevalent. Furthermore, the consistent appearance of "Hoax" as a surname variant for Mary Magdalena underscores the importance of considering variations in spelling when exploring historical records, a crucial aspect of accurate genealogical investigation.   

Martin Carringer and Mary Magdalena (Hoax) Carringer were the parents of nine known children, who constitute the first generation of descendants in this report. These children, presented in their approximate order of birth, are Johann Jacob, Maria Elisabetha, Katharine, George, Calli, Heinrich, Soloman, and Joseph. The historical record indicates that they had eight sons and one daughter (Maria Elisabetha).  

Johann Jacob Carringer was born on October 1, 1785, in Westmoreland, Pennsylvania, United States , and he was baptized on October 16, 1785. He married Elizabeth, who was born on September 19, 1785, in Pennsylvania, United States, and died on October 9, 1868, in Sandy Creek, Mercer, Pennsylvania, United States. Their marriage likely took place around 1808 in Westmoreland, Pennsylvania, United States. Johann Jacob passed away on September 3, 1865, in Sandy Creek, Mercer, Pennsylvania, United States , and he was buried in Sheakleyville, Mercer, Pennsylvania, United States. They had six known children: Anna Maria, Juliann, William, Martin, Joseph, and Daniel. Johann Jacob's life mirrors his father's early residency in Westmoreland County before his own migration to Mercer County, suggesting a pattern of familial movement. His son William's later relocation to California foreshadows a westward expansion in subsequent generations.  

Maria Elisabetha Carringer was born on September 6, 1789, in Westmoreland, Pennsylvania, United States , and she was baptized on December 25, 1789. She married a man with the surname McCartney before 1815, likely in Mercer, Pennsylvania, United States. Maria Elisabetha died on November 20, 1850, in Perry, Mercer, Pennsylvania, United States , and she was buried there. They had two known children: Martin and another unnamed son. The limited details about Maria Elisabetha's family in the provided records indicate a potential need for further research into the McCartney family in Mercer County.  

Katharine Carringer was born on January 18, 1792, in Westmoreland, Pennsylvania, United States. However, another record indicates a birth date of July 17, 1792, and baptism on May 26, 1793. She married Abraham Kazebee, who died before 1825 in Mercer, Pennsylvania, United States. Their marriage likely occurred before 1825 in Mercer, Pennsylvania, United States. Katharine passed away after 1860 in Conneaut, Crawford, Pennsylvania, United States. Her move to Crawford County signifies another branch of the family migrating within Pennsylvania.  

George Carringer was born on February 5, 1795, in Westmoreland, Pennsylvania, United States , although other sources suggest September 5, 1795. He was baptized on June 9, 1795. He married Isabella Montgomery, who died on September 24, 1888, at the age of 85. Their marriage likely took place before 1821 in Mercer, Pennsylvania, United States. George died on January 30, 1870, in Perry, Mercer, Pennsylvania, United States , though another record indicates a death in 1876 at age 81. He was buried in Hadley, Mercer, Pennsylvania, United States , with another source mentioning Long Cemetery. They had eight known children: John Montgomery, James R., Emily, William, Milton E., Isabella, Mary Jane, and Harvey C.. George appears to have remained in Mercer County, maintaining the family's presence in the region.  

Calli Carringer was born on March 9, 1797, in Sandy Creek, Mercer, Pennsylvania, United States. She died before 1810 in Mercer, Pennsylvania, United States. Her early death highlights the higher rates of child mortality during that era.  

Heinrich Carringer was born on June 6, 1800, in Sandy Creek, Mercer, Pennsylvania, United States. He married Sarah Feather, who was born in 1804 in Ohio and died on April 9, 1848, in Mercer County, Pennsylvania. Their marriage likely occurred before 1825 in Mercer, Pennsylvania, United States. Heinrich passed away on August 10, 1881, in Columbus City, Louisa, Iowa, United States , and he was buried there. They had ten known children: Eliza, David Jackson, George, Cornelius A., Mary, Sarah, Henry, Louisa, Matilda, and Harvey. Another record suggests a death date of April 20, 1879, for a Henry Carringer in the same location. Heinrich's migration to Iowa marks a significant westward movement of the family.  

Soloman Carringer was born on August 24, 1802, in Sandy Creek, Mercer, Pennsylvania, United States. He died after 1820. Limited information is available about his life after this point.  

Joseph Carringer was born on October 22, 1805, in Sandy Creek, Mercer, Pennsylvania, United States. He married Anna Maria Spangler, who died on April 18, 1895. Their marriage likely took place before 1843 in Vienna, Trumbull, Ohio, United States. Joseph died on June 8, 1869, in Columbus City, Louisa, Iowa, United States , and he was buried there. Joseph followed his brother Heinrich to Iowa, further illustrating the family's westward trajectory.  

The second generation, the grandchildren of Martin Carringer, continued to expand the family and their geographical reach. These individuals are the children of Martin's nine offspring.

The children of Johann Jacob Carringer were Anna Maria, Juliann, William, Martin, Joseph, and Daniel. William Carringer (1816-1900) married Irene Rich Churchill (died 1899) in 1838 in New York. Martin Carringer (1818-1906) married Mary Rowley. Joseph Carringer (1823-1894) married Sarah Ann (died 1906).  

Maria Elisabetha Carringer McCartney had two sons, Martin McCartney (born circa 1815) who married Margaret , and another son whose name is unknown.  

Katharine Carringer Kazebee's children are not listed in the provided snippets.

George Carringer's children were John Montgomery (circa 1822-1906), James R. (died 1867), Emily (1829-1900) who married a Robinson, William (1831-1886), Milton E. (1834-1905), Isabella (1836-1914) who married Humphrey Orr , Mary Jane (1842-1923) who married Stephen Feather , and Harvey C. (1845-1907). John Montgomery Carringer (circa 1822-1906) married Sarah Elizabeth Spangler and had 14 children, though their names are not listed.  

Calli Carringer had no children due to her early death.

Heinrich Carringer's children were Eliza who married a Robinson, David Jackson (1828-1902) who married Rebecca Spangler (1832-1901) in 1852 , George (1832-before 1880) who married Mary, Cornelius A. (1834-1916) who married Elizabeth Green and later Nancy Donaldson (1852-1908) , Mary (born 1835), Sarah (born 1837), Henry (1839-1862), Louisa (born 1842), Matilda (born 1845) who married John Moore, and Harvey (1848-1870).  

Soloman Carringer's children are not listed in the provided snippets.

Joseph Carringer's children are not listed, though a grandchild named Tastet (1811-1820) is mentioned.  

The third generation, the great-grandchildren of Martin Carringer, further illustrate the family's expansion.

David Jackson Carringer (son of Heinrich) and Rebecca Spangler had three children: Harvey Edgar (1852-1946), Henry Austin (1853-1946) who married Abbie Ardell "Della" Smith (1862-1944) in 1887 , and Effie E. (1858-1874).  

Cornelius A. Carringer (son of Heinrich) had four children with his first wife Nancy E. Green: Nanie J. (married Charles Shrubb), Clara E. (married Ira Wygant), and two others whose names are unknown.  

The children of Henry Austin Carringer and Abbie Ardell "Della" Smith, Martin Carringer's great-great-grandchildren and the fourth generation in this report, were Devier David Carringer (1889-1890) and Lyle Lawrence Carringer (1891-1976). Lyle Lawrence Carringer married Emily Kemp Auble (1899-1977) in 1918 in San Diego, California.  

In conclusion, this report has traced four generations of the descendants of Martin Carringer (1758-1835) of Pennsylvania. Nine children, approximately twenty-five grandchildren, approximately fifteen great-grandchildren, and two great-great-grandchildren have been identified based on the provided information. The family's history demonstrates a clear pattern of westward migration, from Pennsylvania to Ohio, Iowa, Kansas, and California. Martin Carringer's initial role as a Revolutionary War soldier and early settler laid the foundation for a family that actively participated in the development and expansion of the United States. While the provided records offer a valuable insight into this lineage, further research would likely uncover additional descendants and details, painting an even richer picture of Martin Carringer's enduring family.

You can access this Gemini "Deep Research" report  at  https://gemini.google.com/app/02decbb0b2153247.  Check out the "Thoughts" at the bottom of the right-hand panel - they describe what the AI tool went through to provide the report.

Note that the Sources found on the Internet to perform this research include a number of my own Genea-Musings blog posts concerning Martin Carringer, plus WikiTree, Find A Grave, Ancestry, FamilySearch, Scribd, USGenWeb, RootsWeb and other web pages that contain information about Martin Carringer and his descendants.  

There may not have been any mention of Martin Carringer in the material used for pre-training the AI tool.

4)  However, two of the sources noted do provide a fairly complete descendants report --
Six Generation Descendants Report of Martin Carringer (1758-1835) and Maria Magdalena Houx (1768-1850) of Mercer County, Pennsylvania - Genea-Musings
 (done in 2023) and 
Descendants of Martin Carringer (1758-1835) - 4 Generations | PDF | Genealogy - Scribd
 (done in 2012 which is not as complete as the later six generation report).   

Unfortunately the AI tool did not take full advantage of those reports - the six generation descendant list report on the first post above used the Henry numbering system, while the Scribd descendants report on the second report above used the NGSQ numbering system.  

I think that the "Gemini Deep Research" descendants report listed all of the children of Martin Carringer accurately, but did not find all of the grandchildren, great-grandchildren or great-great grandchildren.  It listed 25 grandchildren in the report, but the narrative descendants report on Scribd numbers 45 grandchildren.  There are many more great-grandchildren (scores) than 15, and many more great-great-grandchildren (hundreds) than 5.

 Why is that?  My thought is that it does not yet know how to read a descendants list report with indented generations, or how to "read" the Henry or NGSQ numbering systems.  Perhaps the material was too long for it to navigate.  Maybe it doesn't count things well.  Or there is no web page, blog post, WikiTree profile page, Find A Grave page, or Ancestry profile page for each descendant of Martin Carringer.

5)  I haven't tried this particular query on ChatGPT4 or Grok yet.  My guess is that the results will be similar to the Gemini report.  This report provided a decent description of the subject ancestor and his place in history, but an incomplete list of descendants.  Perhaps a prompt that explains the Henry number system would help (or even mentioning use of the Henry number system - does Google know what that is?).   

6)  My conclusion is that the AI "Deep Research" Tools cannot do this task reliably at this time.  This is a benchmark for future reference - if I try this same prompt in six months or so will the response be the same?  Would a paid account on Gemini improve the response?
