'Robert Martin was brother of ABRAHAM MARTIN {1635, Weymouth} and of Richard Martin, who came to Rehoboth in the 1660s. ... Another brother was probably ISAAC MARTIN {1639, Hingham}, who appeared in two New England records: in ... 1639 [Hingham] ... and in 1643 ... in Rehoboth [Early Rehoboth 4:4].'
