Hello!
Egalton is a very rare name, so I was suprised to see your post. As you can see I share the same name so Nancy must be a relative. Most of the Egalton clan now live in the Dagenham area (border of East London Essex). We moved here in the 1930's, but come from that part of the east-end your interested in. I don't have any imformation on Nancy, but if I can be of any help please get in touch.
Terry
