I had a look to see if anyone else had researched John Logan and Isobel Booth from Old Deer. And yes, there are lots on Ancestry, all with a birth date for John Logan of 1796, which is correct, but with most of them having him born in Ireland. He wasn’t: in fact I doubt if he ever went out of Aberdeenshire. How they manage to get such an error is beyond me, as he was alive in 1841 and it says he was born in Aberdeenshire. Plus there’s a 1796 baptism for him at Old Deer on FamilySearch. Very, very sloppy research by an awful lot of Ancestry users. Once again, it looks like one person has made a mistake, and then heaps of people have come along and copied that tree without bothering to check whether it’s right.
There’s been quite a bit lately in genealogical circles about the “One World Family Tree” idea. Apparently FamilySearch now have something where everyone enters their tree onto one big tree, so that eventually everyone in the world (or at least the genealogists amongst us who can be bothered) are connected. But there’s a big problem with that idea: how on earth can they keep it accurate? If the people who put error riddled trees up on Ancestry are anything to go by, the vast majority of family trees out there are wrong, and some of them are very, very wrong. I’m not tempted to join a “One World Tree”. Has anyone had a look at one?
