Thank you for replying. We do live quite near one another. My gg grandather was Abraham's brother George.
I have researched back to James and Rachel HIZZEY, although I don't have proof of date/place of birth for James. (Have a copy of the banns of marriage) John and Mary seem to be mentioned in other people's trees, but with no evidence.
I noticed that some of the ADBY's have been known as ABDY and am trying to find a link between them. Have suggested to another member that maybe a DNA test would be the answer, but would like to explore this further before anyone spends any money. HAve you managed to find any information on John and Mary?
