His first wife was Anne, maiden name unknown. They had 2 children, John and Sarah. He married (2)Abigail Norton Beers, and (3) Elizabeth Beecher by whom he had several more children. His origins are unknown, but he is NOT the son of Robert and Rose Dunbar of Hingham. This has been proven many times over by both records and DNA. Male descendants of both lines have been tested and they are unrelated.
