Well I think that's great, Christine.

I imagine James Armstrong died, Eliza took up with John Young and had son William before she married John, if she actually did marry him, I couldn't see a marriage for them.
While I was typing this you've been sorting out the birthplaces, as I have been doing, I just thought I'd type what I saw before making any guesses, and you say the same as I was going to put now, that Heighley is probably right - have you seen the census image? Edington is near Mitford where Ralph was born, so I've modified my earlier post - it's indexed as East Chivington on ancestry!
