New to the list and was wondering if anyone might have or suggest sources for any biographical information on my 10th g-grandfather John Cogan (Coggan) d 27 Apr 1658 in Boston. He married Martha, the widow of Gov Winthrop, in Boston on 10 Mar 1652. I have found that he supposedly opened the first "Shop" in Boston at the NE corner of what was to become Washington and State St. but have never found any reference as to what type of "shop" it may have been. Any information or suggestions would be graetly appreciated, Thanks in advance, Monte LeBlanc
