I am not a Furber researcher, but was looking for a place to put this information and your message caught my eye.I am also a descendant of Edward Starbuck and Katherine Reynolds.I had not seen the name of her mother previously and will have to check that out.
There are quite a few Furber listings in the index of one of my books "Landmarks In Ancient Dover, New Hampshire" by Mary P. Thompson, 1892.This was reprinted in 1991 and I purchased it from Heritage Books in Bowie, MD.
"Furber's Point and Ferry - on the Newington shore, at the Narrows between Great and Little Bays.The name is derived from Wm Furber, who came from England in the 'Angel Gabriel,' which was wrecked at Pemaquid in August, 1636.He was at Dover in 1637, and belonged to the Combination of 1640.He had a grant of land at Welsh Cove as early as 1652.In 1657, he had a grant of thirty acres more, which must have been beyond the boundary line at Hogsty Cove, as they were a part of the 400 acres along Great Bay granted to Dover by the government of Mass. Bay in 1643, and confirmed in May, 1656.These 30 acres were doubtless part of the land he afterwards gave his son Jethro.June 17, 1674, he gave his homestead to his oldest son William (see Pascataqua Rock), who, Dec. 11, 1694, was licensed to keep a ferry 'from his house at Welchman's Cove over to Oyster River.'Furber's Ferry, however, was in operation before May, 1694."
