Pat,
No, you're not confusing the issue at all, in fact it's more food for thought. I did a bit of searching on Google yesterday for Quarry house in Acomb and looked at both St John Lee and Bywell St Peter - the address seems to appear more than once in many areas in and around both places. There are definitley links with Shotley Bridge as my Michael Glendinning, although stating he was born Peepy, Northumberland on all his census entries, appears to have lived in Medomsley/Shotley, from what year I don't know. I know he was there in 1837 as he married Ann Postle in the Chapel of Medomsley in 1837 and they were resident in Shotley Bridge at the time of the marriage. Ann was also born Shotley, so there are definitely links with then info you sent. Some of the Postle inscriptions I already have as another kind person on here transcribed them and gave me the details.
Thanks for the info - every bit helps
Nadine
