Do you know if anyone in your group had a daughter Sarah P. Brown who married John Keen of Thomaston Rockland area. They are buried in the Achorn cemetery in Rockland. My ancestor Sarah S. Keene married Almon Bird she died in 1868. On her tombstone it says her parents were John Keene and Susan S. so I think she was the first wife and Sarah P. Brown was the second wife. A William Brown is buried in the same lot with Sarah P. Brown Keene. No further info on William Brown in the cemetery record. John had another marriage to Harriet Reed. Does any of this hook up with what you know?
