Hi Teresa and Sandy,
Many thanks again. I do believe that you have the right Benjamin here as his parents were Benjamin and Mary Masters. Seeing as both he and Elizabeth were married in Brackley i would say that this is probably the right Elizabeth too.
I wonder if i can be cheeky and ask you if there are any other Tyrrells married or died in Brackley as it looks like the family may have moved there from Aynho. I don't know the area that well as i live in Bolton, Lancs. Other siblings of Ben and Elizabeth were; Mary, Henry and Thomas, born; 1768, 1770 and 1772 respectively ( all Aynho).
Thank uou so much again.
Best wishes
Julie
