Your post is a bit old but perhaps the following will still be of interest. Johanna van Someren was born Jul 25, 1821 in Puyfluyk, Holland. She died on July 23, 1906, in De Pere, WI, and is buried in Freedom, WI. She was married to Joannes 'John' Hoks, born abt 1814 and died Jan 23, 1882. This info comes from Holy Cards.
I believe they had a daughter, Mary Hoks, who married Jacobus Gerhard Van Susteren.
Would be interested in anything else you may have connected to Hoks.
