I can't tell you anything beyond John Shibles (b. Pemaquid d.Thomastown/Thomaston 1777). I do, however, have Mary Carney b.1742 d Aug 1799, her parents and their marriage. Mary Carney was my 3rd great grandmother. I assume she is yours as well. She married (as John Shibles widow) my 3rd great grandfather, John Dillaway/Deloway in 1778. He was from Boston and was sent to Thomaston during the Rev War. They had three children who would have been half-sisters and a half-brother to the Shibles children. John Dillaway was the Thomaston town clerk and a state representative. There is a record in The Mayflower Descendant, vol46, No 1, 1996, of Mary's parent's marriage in Easton, Bristol, MA in 1742. Thomas Carney and Nellie Murfey(O'Murphy)were married by an Edwars? Hayward, Justice of the Peace. I have yet to find the ship that brought them from Cork, Ireland. It had to be prior to 1742 and the names are probably garbled. They were early settlers in Broadcove, Cushing, ME. Let me know if you want more.
