This name and his relations are a puzzlement to me, as the name Thomas Seabrook is repeated so often in the family.
Robert Seabrook's wife's name I believe was Alice Goodspeede dau. of Nicholas Goodspeede and his wife Margaret. Possible that Robert's father was a Thomas, but not sure which one as that name is repeated at least 1 time in almost every family of Seabrook's that i have come across at that time period, making it very difficult.
Alice Goodspeede Seabrook was b/christened. August 19, 1576 in Wingrave, Buckinghamshire, England (WFT Vol. 1, Ed. 1, Tree #: 1684)and d. 1659 in Stratford, CT (WFT Vol. 1, ed. 1, Tree #: 1684).
Currently looking for information on both Fairchild's and Seabrook families.
Also, there was a book written not too long on the Fairchild Family. if you get a chance, may be worth your while to take a look at it has a lot of information on this line. The book is called "Early Fairchilds in America and their Descendants" by Jean Fairchild Gilmore, pub. Gateway Press, 1991, Library of Congress #: 91-75723
Jean's address in the book is given I have only the pages dealing with my direct line however. LDS center in utah has copy of book but it is not filmed at this time. :( The copy that I saw was located in a Library in Paintsville, Johnson Co., KY
