For Carol,
Further update -
Banbury Baptisms 1723 - 1812 show two John VARNEY's being bapt.
17 Jan 1738/39, VARNEY, John & Sarah, s & d/o Stephen, tailor and Mary. and
7 Dec 1751, VARNEY, John, s/o Stephen, lab, and Grace.
I don't honestly believe that either of these is the John you are looking for.
Similarly another was born in Milcombe, one VERNEY, John, ch. in Bloxham, 29 Dec 1738, s/o William of Milcombe.
Although I have found the surname in several of the PR's I have examined none of them show a John & Sarah. This pair seem to be very elusive, were they by any chance travellers or boat-people? the reason I ask is that they crossed through two other parishes from Great Tew to get to Hook Norton in the seven weeks from getting married to the christening of their first child, Sarah was from Gt. Tew and John seemingly was from Mentmore in Buckinghamshire according to the OMI. Anyone on the thread got access to the Chipping Norton PRs as a possible location for further baptisms; I am going the other way, back to the canal system running from Williamscote north of Banbury down to Weston Green and beyond and the associated parishes until we can find a more substantial link or information
For now then,
Cheers,
George.
