Kyle, thanks for the children's names, but you said there were ten children? You only listed nine names.
Yes, http://home.earthlink.net/~grolstonhttp://home.earthlink.net/~grolston is my family web page. Has not been updated in a while, and I have a lot of new information as well as some corrections.
William Rolstone is said by some to be the son of John Rolstone of Boston. Spent a great deal of time trying to confirm this and was able to document all of John's children but no son by the name of William. I have yet to find anyone who claims this father-son relation to be able to provide any documentation to that fact.
John Rolstone, depending on who's genealogy you look at, died about three different places? Does little to boost my confidence that John was the father of William.
None the less, I do have numerous generations of the Boston Roulstone family on file. I think it starts in the 1600's. I can email that info to you. I have the file broken up into five generations, as I recall. My email is firstname.lastname@example.org.
I had not looked for Frances McNair's parentage. So I will take a look at the web site on her family.
