I am also researching my ancestors. The Fyffe's are from my mother's side.
I may have read over this, but I am on ancestry.com and looking to find James William Fyffe's parents.
The information that I've come across is that he is from Londonderry, Ireland born in 1713 and passed away in Maryland in 1781. He is also married to Sarah Watson - they married in 1745.
Does anyone have any other information?
