I am looking for information on Cornelia Visser born between 1846 to 1850 in Dordrecht zuid Holland. Pieter Visser and Christina DeHaan are her father and mother. Cornelia immigrated to Pella Iowa about 1868, married Henry (Hendrik) terBeest who owned the Skunk River Sawmill east of Pella. Cornelia was a domestic servant in the Phillip Koelman family in Pella, Iowa based on 1870 Census. Any information, large or small is appreciated.
