I'm trying to trace my gggrandfather John Andrews, married about 1835 in Dublin, to Marion (or Mary Anne or Marianne or similar)Watson. He was a pawnbroker or possibly just a pawnbroker's assistant. I have no birth date or place for either, but evidence that they were both Irish.
They had at least six children, starting with Nathaniel Watson Andrews b 1838, who emigrated; Adelaide, Frederick (my ggrandfather), John, Arthur - and Eva in 1851 or 1856 according to which Irish census you look at. Possibly also a William, not traced.(info from my grandmother, and a Vermont census for 1900). I have found no birth records for any of these children on Irish sites or FamilySearch.
