Did anyone know the Woodhouses in Chesterfield Gardens?

As part of my continuing research into the history of my house in Chesterfield Gardens, I'm trying to find out what happened to Valerie and Shirley Woodhouse, two sisters who were born here in the 1940s and lived in the house in the 1950s and at least part of the 1960s.  Their mother left for Scotland in 1997, and I still used to get the occasional item in the post for them in the late 1990s.

Grateful for any information! 

If you'd rather message me privately, please do so.

Thanks
