I'm looking for information/leads/suggestions on Hammer's from Cuba or Spain that ended up in Northumberland County, PA. Here is what I have so far:

Elizabeth Hammer (born 1810 Cuba or Spain)On last census in 1880, Elizabeth's surname is listed as Racoff?
Husband unknown (from Cuba or Spain)
Daughter Margaret (born 1830 in PA). Married Henry Petery of Sunbury - Northumberland County, PA.
Frederick or Federick Hammer (born 1829 in PA or DE(son of Elizabeth)

I'm from Margaret's line.

Thanks for any help!
