George Worthington Dow and family

I am looking for information on George Worthington Dow (1811-1884) who in 1833 married Anna Debevoise Prince in Brooklyn NY and sired 14 known children.Although I haven't confirmed it, his father may have been a Josiah Dow and his sister may be the Ellen Almira Dow who married Abiel Abbot Low, a shipowner and merchant in the China trade who became quite rich, dying with an estate valued at about $8 million (roughly $200 million today.)A related question is whether the grandson of George W. Dow, also George W. Dow, was the man who about 1896 married his second cousin, Alice M. Osborne.
