I have information on a Martha Dow b. 1 Jume 1648 who m. 2 Dec 1673 Joseph Page. This was her 2nd of 3 marriages. However, there appears to be some problem with this being the Martha you referred to, since although her father's name was Thomas Dow, Thomas is untraced. He is not the brother of Henry Dow who came to America in 1637, since that Thomas Dow was baptised 16 Jun 1601, lived in England his whole life, had a family, died and was buried there - and his descendants still lived there in the early 1900's.Thomas, father of the Martha I have information on, died 31 May 1654 ae about 39 - so could not have been baptised in 1601.
