Fam. Maschmeijer

I wonder if anyone knows what happened to the Maschmeijer family. My father was born in "Villa Omval" in 1926. He spent his early years there and was like a little brother to the daughters of August Maschmeijer. He remained friendly with them for a number of years but eventually lost touch. He still mentions Lucy, Margot, Aranka and Mia sometimes. I wonder what became of them.
