I have here the roots of your family in The Netherlands. (The other reply with roots in Friesland, is NOT your family)
Your great-grandfather Jan de Bruin was born on 07-07-1847 in St.Louis MO. The arrived with ship Maasstroom in April 1847 in Baltimore. First stop was giving birth, final settled in Lake Prairie Township, Pella, Marion, IA.
My late wife was a de Bruijn, that's why I started a tree about this (hugh)family.
