Came across your post through a search for John Bussing Haskin, Congressman from New York. I have seen vital records for John, and I believe his daughter Maria Anne, in the LDS Site, I believe the URL is www.familysearch.org.
I am looking for a connection between my family and Johns father Henry Remsen Haskin. I have in my possession a letter proposing marriage from Henry to his future bride Elizabeth Bussing. If you have any information of other children of this couple I would love to hear from you.
Some other names I am researching in that area PENTZ, O'KEEFFE, SWEENEY, BLAIR, KERBEN, PERRY, CARTER.
