Hi Becky, is this the Jessie David Wilson who married Hannah French and had Arthur, Lenora, Edwin, George, Bernard, Hattie, Wallace, and Helen? I'm researching the Wilson's from Sagadahoc, also.
My husband is related through John Wilson whose brother was William F. Wilson. Our records show william was born 24 may 1807, in Bowdoing, Sagadahoc, ME., d. 1884. Our research was done by my husband's uncle John and gave the father of William and John as Andrew Wilson, b 1781, which is where I've run into a wall.
Let me know if any of these are common ancestors so we can compare notes!
