Look in Winslow,and Fairfield Maine for early brothers from Duxbury,Mass.as she is probably dec. from them.Look for spellings, Gullifer,Gullison,Culliver and Gulliver. John and wife Betty Delano Gullifer of Fairfield and Thomas Gullifer b.Duxbury,MA of Winslow and wife Patience Tozier/Tozer of ME, sons of Thomas b.1720,Duxbury,MA and Keturah Sampson/Samson of Duxbury who went to Me.He was son of Henry and Mary/Marcy Tracy of Marshfield, Mass. They had a brother Peleg who stayed in Duxbury,see 1790 Fed.Census for he and his widowed Mother Keturah.These families are desc. from Mayflower pilgrims, Miles Standish,John Alden and Pricilla Mullens and her father William Mullens through Lorah Standish who married Abraham Samson/Sampson whose son, Nathaniel mar. Keturah Chandler and their daughter Keturah sampson mar. Thomas Gulliver/Cullifer b.1720 I suspect some of the Gullisons in Maine are also Gullivers whose names were corrupted at an early time as John Gulliver of Fairfied,Me is called Gullison on the 1790 Fed.Census. I hope this helps you with some clues.
