Johan:My father-in-law was born in Antwerp as Francois Louis Van Steenkiste.His father was Louis Francois Van Steenkiste and I understand that the generation before would have been Francois Louis, etc.
My father-in-law and family fled to England when Germany invaded during WWI.They returned to Belgium and decided to immigrate to US before WWII when my father-in-law was a young man about 18-20 yrs. old.
He was an artist and became a commercial artist with an office in New York City.His name was not easy for business so he americanized the name: Frank Van Steen.
Hope this helps in you quest.By the way, can you tell me what Van Steenkiste means?Of the stone ...., I believe.Thanks
