Looking For A Family

A Memory of Harborne.

I'm trying to locate a family from the Harborne Lane area, Selly Oak. I have very few details. The family name is Davies the father was Stan, I believe he had 2 sons. He had a sister or aunty called Betty, I think his mother was called Margaret and father Arthur. I believe they had a garage selling or repairing cars, and this was sold a few years ago. I would be extremely greatful for any details anyone may have?
