If you should find a connection to the Rothbury Swann's then the 1816 Bible Cenus may be of interest:
"Page 68. Alexander SWANN is an industrious Weaver in his sixty-eighth year, is married and has a daughter thirty years old, complains that Rothbury Beer bought at two pence a gallon is bad!, is going to live under Mr. STONER, has a clean copy of the Whole Duty of Manna Bible, a Testament and two Prayer books, and wants a Bible in large print.
Total: 3 Persons, 1 Bible, 1 Testament, 2 Prayer Books
Page 43 John SWANN is a joiner, he and his journeyman are Presbyterians but his Father, Mother and sister, who live with him attend the Church. The sister spins a pound of yarn per day with a double handed wheel. there are three Bibles and two Prayer books in the house which has every appearance of comfort and industry.
Total: 9 Persons, 6 Bibles, 2 Prayer Books "
I have an ancestor Ann Wintroup who was born April 1703 and her mother was Eleanor Swann who would therefore have been born in the late 1600's. They too lived around Rothbury.
