Schrader Kingdom of Hannover

Searching for William Dietrich Schrader b-Jun 1801 and his wife Sophia Fancis
?last name? b-Aug 1812. They arrived from Bremen on ship "Columbia" in NY,NY
on 6 Nov 1833 with children Charlotte b-22 Feb 1825, William b-1 Sept 1828,
and Henry b-24 Aug 1833. All records - death, obits, census, land sales,
etc. list "Kingdom of Hannover" or Germany except Sophia lists Baden as her
birthplace on 1880 census. Have hit a brick wall on this. Will appreciate
any help.

Thanks
