Ancestry has numerous references to one or more Grizel Durham.
Thank you.
I searched there for Grizel Durham (with name variants) in Scotland and there were 102 'results'. When I looked at those there were in fact only 28 results for that name. The remaining 74 supposed results were for people with an initial G somewhere in their name.
Of the 28, one is from a tree and gave the name of her spouse Alexander Fotheringham, and her birth date as 1624. As I have a copy of Alexander Fotheringham's will dated 1624, which mentions his wife, this is clearly nonsense.
Six of them are member trees, which I may look at next time I have access to Ancestry. However I never trust online family trees, and there are already plenty of contradictions in the ones I can access without resort to Ancestry. (One calls her 'Countess' which is incorrect.)
All of the rest are extracted from indexes more readily available, and free of charge, at Scotland's People.
Correction: there are 44 are results for the name. It seems that Ancestry, unlike FamilySearch, doesn't arrange results so that the closest matches are all grouped together, but scatters them at random among the ones with an initial only. Of the 16 additional results, 15 match listings on SP, and the other one is another tree.
