John Browne-Plymouth again

It looks that John may have been a Bristol England native. He was involved in the creation of a trading settlement in Maine in 1625, several years before the Plymouth colony was created. Considering that names in the colony associated with him were named for locations in England around Bristol, such as Bristol, Taunton and Swansea, it would seem that this may be a viable option. One suggestion was that he descends through the Eastern family of Beachworth Castle through William who removed to Tavistock. In the book Mary Browne: a true account of her life, Thomas is recognized as his father and William the famous poet his brother. But there was also a Browne family that existed in Bristol since before surnames were created. Still on the hunt.
