This info from the "Scotland, Births and Baptisms, 1564-1950" database, shows that a Gilbert Wilson and an Isobel Ramsey had son William in 1690 in Glasgow. Gilbert, the subject of this profile would have been about 70 years. Then a Gilbert married (another?) Isobel in 1703?
According to this WikiTree profile, Gilbert had 5 children, born between 1650 and 1688. Something doesn't compute. When this GEDCOM was uploaded. there were what appeared to be duplicate people, but with some different/wrong details. I think this may have led to some bad merges.
This entire family needs to be reexamined.
