Do you know the meaning of "circa" in genealogy? It is used before an "approximate" date. Not a date that has been proven.The "source" of circa 1709 is based on the approximate dates of his children. 1709 was not taken from another James Abercrombie/Abercromby. It is only an approximate date.My family tradition claims he was born in Scotland, but as I have previously stated in posts it was passed down through generations.To date no one that I know of has found a true source for the year of his birth.Would leaving it blank satisfy you?
By the way what source do you have for "circa" with John circa 1740??
I too am aware of the 1936 DAR claim that was invalidated as well as many others from other lines, but the year of circa 1709 is not based on that claim in MY family traditon, which preceeds that year. Where do I rate it?Family oral or written traditions can be very accuarate to being total wrong.You forget mine also involves the Dials as well as the Abercrombie line and what is contained regarding the Dials is very accurate.Based on this accuaracy the number on the scale goes up regarding what it contains on the Abercrombies.As for your circumstantial evidence it could be based on a number of assumptions and even one could put the conclusion at a big zero.
John, James circa 1740, and Issac are based on wills, census and land records.Rebecca and Crystie are from a combination of my Dial/Abercrombie family tradition and wills. So I did not just use family tradition.
I was just stating that IF Isaac did not marry till he was into his 30s and his will had no mention of children from a previous marriage, which could indicate this was his FIRST marriage it could also hold true for James ca1740.
As for Issac's first son given name of Archibald did you consider it was a name in his wife's family and not his?You are so hung up on naming patterns.I have lines where the first son was named for a friend, a famous individual or maybe just because they liked the name.Naming patterns were not the law, but you are totally stuck on naming patterns. Naming patterns were more of a tradition with royals then the more common person.
