The date of Martha's birth should indeed be 1798, not 1898.Sorry about that.Martha died on April 15, 1868, and is buried in Union Dale Cemetery in Pittsburgh.At the time she died she was 70 years, 1 month, and 24 days old.I obtained this information from the cemetery records and her tombstone inscription.From the 1850 and 1860 census I learned that she was born in Ireland.
My statement that Thomas McFann might be her father is really pure speculation. I refer you to a post on the Chambers forum by John Byrd on December 10, 2000.He lists two of Martha's children as Thomas McFarn Chambers and Mary McFarn Chambers.I then found a Letitia or Letita McFann living with John and Martha Chambers at the time of the 1860 census.This made me think that "McFarn" in the Byrd post should actually be McFann and that Martha's parents may have been Thomas and Mary McFann.When I found Thomas McFann in the 1815 Pittsburgh directory who had the same occupation as John Chambers (shoemaker), I thought it was a good bet that he was Martha's father.
Unfortunately, John Byrd never responded to my post or an email, so I don't know where he got his information.If I did I might be able to confirm that "McFarn" should actually be "McFann."
I have been looking through Pittsburgh city directories at Carnegie Library in Pittsburgh for my ancestors.I intend to look at some of the directories besides the 1815 directory to see if I can find any other McFanns.If I find any, I'll post the results on this forum.
