"I wrote away to obtain copies of primary sources like vital records and began to notice they did not square with the relative's research. I emailed him and he said all sources were in the ancestral file, so I booted it into Legacy. But the sources were written in some strange words and when I Googled them a multitude of ways they always returned zero results. I emailed again, but all he had to offer was an apology that he "couldn't remember that particular file" and then he wished me to have fun. WHAT?? I email back, and this time all he says is that his relatives "did not deliver much information" (aka. "nothing") on that line I was researching, so he got all that was there in the book from the Internet, and wished me good luck! SERIOUSLY?!? He had NO intention of standing behind his research!
"I bet you can figure where I am going. I finally discovered his "source." It was an Ancestral File from the Family Tree section on the www.FamilySearch.org website. Exactly, one of the same ancestral files for which the website states "Data in the File has not been verified and should only be used as a starting point for additional research." In other words, they are "clues." My wife's relative had published, and was charging money for, a family history book with inaccurate clues represented as facts! I could scream! Now everything he did has to be verified, every source double-checked. Wonderful."
