Borth profiles are Browne, not Brown.
They do seem close enough, but several dates are off (one of the profiles has a granddaughter Thomazine who apparently got married at the age of one, for one thing) and apparently there is some question as to whether the William Browne, son of beheaded Thomas Browne, is the same man as William Browne, father of John in Tavistock.
Just in case, I'll leave this merge to those who are more familiar with the era and sources in question.
