My 4x Great Grandfather Michael Light came from Germany to NYC (Brooklyn and Manhattan) some time in the late 1840's, but I don't know about his life in Germany prior before his arrival. His German last name was Leicht or Licht I don't know who his mom and dad is. All I know that he was born in 1807 or 1810. He married Pauline Davis (Americanized name) before coming to America. Another relative that also does genealogy suspected that they were Jewish. Any help on this will be appreciated.
