Merry Christmas, Bryan
It appears as we may possibly be cousins in one generation or another. Thomas Peterson FORBES was/is my grandfather & his first wife, my grandmother, was/is Elizabeth Mae BAILEY.
His parents were/is William B. (no idea what the middle name is) FORBES & Jane Duncan MITCHELL. Jane's parents are Gideon MITCHELL & Chloe DUNCAN.
The best I can do with William B. FORBES parents is John FORBES b. abt 1800.
