Hello, I try to find out if GUILLAUME VAN HERTERYCK who came with the vessel "Tenacity' to New York did create a family and if he has children.
Guillaume came from Belgium (Flemish) to New York on the 30 Jan 1947 and he was 15 years old.

I have now already all information about all VAN HERTERYCK (born married and died) between 1796 and 1904. I have difficulties in obtaining information from 1904 until now.
