Re: Pepperrell family.
My mother is from Kingston-upon-Thames and knew a Pepperrell family. Their house was bombed in WWII and several family members perished. Also, we visited Kingston cemetery last November to look for my grandparents' grave. I recall seeing a headstone for Harry Pepperrell and his wife. I think they died in the 1970s. Would any of these people be the ones you're referring to?
My mother is still living so you can e-mail me directly if you have any questions of her.
