Lyman Abbott is my great (great, great??) uncle. Jacob Abbott was Lyman's father; Lyman had three brothers. I have a personal letter from Jacob's sister (Aunt Sallveia(handwritten) which I am trying to transcribe telling the family line backwards. The other names you mentioned, I am not sure about The letter is addressed to Edward, Lyman's brother. Have you been to Bowdoin College? Are we talking about the same ones?
