The information I have on Thomas, is that in 1660, three brothers born in Enfield, Middlesex Co. England came over. One settled in Swansea, another in Concord, and the third, Joseph, went to Harvard. The name at the time was written as Easterbrooks. This document does not give the other two brothers names. Later in the history, it brings up Thomas Easterbrooks, having died at the age about 84years on April 11, 1713. This puts his birthdate around 1629. This Thomas had four children like Rene said, being John in 1668, Thomas Jr. in 1670, Elizabeth in 1673 and Sara in 1676. Sorry but it does not give the name of his wife.
