There are a number of Free databases available on the site - from the Explore page I clicked on the Massachusetts Vital Records to 1850 database. This is a collection of images from published books for many of the towns of Massachusetts up to the year 1850. In most cases, these books have sections for Births, Marriages and Deaths, and the information is printed alphabetically by surname. Not all Massachusetts have had books published with their vital records, but many have. These records were extracted from the handwritten town records, from available church records, and available cemetery records.
Here is the Search form for the Vital Records of Massachusetts to 1850 database:
I filled in the "First Name" field with "Isaac" and the "Last Name" field with "Seaver." The system had already filled in the database name for me, so I only receive matches from this specific database. There is a check box for "Use Soundex" and the user can specify a year range, or a city or town, or a volume and page number if known. I clicked on the "Search" button at the bottom of the search box, and I received 21 matches in all of the available town lists (two screens shown below):
In the image above, the portion of the page shown in the image box is shown in the upper left hand corner. There are icons in the lower right-hand corner of the page image frame can be used to Save the image, rotate 90 degrees CCW, rotate 90 degrees CW, Zoom In, Zoom Out, Switch On/Off Full Screen Mode, and Return Image to default zoom and location.
Below the screen image is an index of the entries on the page (two screens below), with columns for Names, Original Text, Start Date, Location and Record Type:
The extracted records on the web pages have a link to the Town book information - here is the page for Leominster (which opens in a new window):
This page provides the title and publication information for the book, but not a perfect source citation. There is also detailed information about the records included, the abbreviations used, the town book start year, population statistics for the town, and the number of births, deaths and marriages recorded.
