My granddad is actually from Liverpool but it is his dad I am trying to research. All I know is that my granddad's family are from Katwijk 16km north of The Hague. All I know is what they did in England.
My Great-Granddad Hendrik Vlasman married Maria Hughes (born in England) in Liverpool in 1943. My Granddad's name is Hendrick Vlasman he has a brother called Victor Vlasman who still lives there but we have lost contact with him. My Granddad was born in 1944. My Great-Granddad and my Great-Grandmother Maria got divorced in Katwijk, Holland but I don't know what year. So she brought my Granddad back to England and Victor stayed with his dad. I know Victor has a child called Victor who married Bernadette in Holland and they have children. Henry (my grand-dad) married Eileen Dutton in England and had seven children in England. That is all the information I have I hope its useful.
