Thanks for your reply Wozzle,
since I posted this query in August, I sent off for the Stanion PR, where there does'nt seem to be any earlier Tebbuts than this John & Mary couple, then nothing till 1740 when a cooper, Robert Tebbot marries and has children in Stanion.
What the PR did show though was that John Tebbut was a 'keeper' , unfortunately the only Northants. Will for a John Tebbut, keeper was from 1749 in Fawsley who doesn't seem to be the same J.T. in Stanion.
What I'm hoping to find is John or Mary Tebbuts burial in Kings Cliffe where I have Alice Tebbut marrying a John Cunnington, and seemingly spending the rest of her life.
Best
John
