One question that I have concerns the death place of William Alexander. If this is the Williamwho was known as "the corpulent", then I wonder whether he died in Va. or in Ireland. Many researchers post that it's Va., while others claim it's Cty. Donegal. However, I've yet to see any source data.
In the various books concerning this line of Alexanders, I always read that 3 of William's 4 sons emigrated to Pa. ca. 1731 (theylater removed to Va.). But, there's never a mention that the father joined them.
