Hi, I am from the Netherlands and try to find roots of the ancestors of the family of my mother in law. The name of the mother from my mother in law was Francina Cornelia Sul, born November 27th 1897 in Utrecht (NL) and died May 2nd, 1994 in Alkmaar (NL). She was a daughter of Jan Sul (born Febr. 24th, 1853 in Schokland (NL), died Dec. 30th, 1922 in Utrecht (NL)and Cornelia Marchina Phillippi (born August 15th, 1861 in Zwolle (NL), died May 9th, 1940 in Alkmaar (NL). The parents of C.M. Phillippi were Hendrik Phillippi and Petronella Maria Haas. There are no dates of birth or dead available. Are these Phillippi's related to your family? Phillippi is not a commom Dutch name; it could be a Swiss name.
I hope you can help me (I did find a lot of info about the Sul-family up until 1625). Regards, Jolanda Kaarsemaker
