Trying to find information on Jan VAN KAMPEN, b. 1863 Westerwijtwert Groningen. He immigrated to the US in 1880's. His father, also born in Westerwijtwert was Kornelis VAN KAMPEN, son of Geert Jans VAN KAMPEN. Any information on the above is more than welcome. I have many descendants, yet am looking for more precise early family history.
