Re: Silas Fowler b. 1810 Fayette county, PA
Have you performed a search for the name "Shuff" on the Pittsburgh digital library site? I did and there were many "hits." Here's the site:
No, I'm not aware of any siblings for Silas, but I do suspect that he worked in the iron industry in that exact location you refer to. He may have had an aunt named Mary, or maybe a sister named Mary because I have some information about a Mary Fowler from Georges Twp. Fayette County.
Was this Mary Jane you speak of a Fowler?
