Alan,
I'm extremely interested in the information you've uncovered that Lydia (Clough) Mattoon was a daughter of John and Dolly (Lawrence) Clough. A cousin of our line, Sarah (Newell) Coats of Syracuse, N.Y., granddaughter of my ancestor Benjamin Lawrence, named Abner C. Mattoon executor and heir in her will and refers to him as "my cousin." I've felt for a while that the relationship must be through the Lawrence family rather than the Newells or Mattoons since Lydia named her son by Oren Monroe, George Lawrence Monroe. Your information appears to confirm this. I suspect that Dolly (Lawrence) Clough is the Dorothy Lawrence born July 29, 1766 in Groton, Mass., daughter of Isaac and Mary (Bailey?) Lawrence, and that her brother Benjamin, born in Groton July 15, 1761, is my ancestor. According to The Genealogy of the Family of John Lawrence, by John Lawrence (1857) and Claremont, N.H. cemetery records, several families of Lawrences from Groton settled in Claremont. Do you have any additional information on Dolly or the Lawrences? I'm happy to share any info. I have, either through this board or by email at Rodjr732@aol.com.
Many Thanks,
Rodney Dillon
