I am looking for any information regarding a John Crosman b. abt 1581, married to Thomosine Marchant, b. abt 1585, both from St. Andrews, Plymouth, Devonshire, England. I believe they are the parents of Robert Crosman, b. Nov. 1, 1622, who immigrated to the Americas in 1642 and settled in Taunton, Mass. U.S.A. According to the information I have received, Robert Crosman (spelt with one 's') is my GGGGGGGG-grandfather. and in 1762, his descentant, Samuel Crosman, who married a Alice Potter, moved to Falmouth, Nova Scotia, Canda.
Any leads to John and Thomosine would be appreciated.
