Thanks for your kind relpy, Davierj, That was quick!!!
I am stumped! This family was very mobile, it seems. My first verification was that Jonathan & Hannah were married in St Denys Parish 1790. Warminster. Next verification, at Fonthill Bishop Parish, where Jonathan is buried in 1833 at age 76. A bit of Math would indicate that he wa born C/ 1757. but where? IGI gave 2 places- Chicklade & Cricklade. Parents were William Perrit & Elizabeth[both born at Castle Eaton].so it seems they were all over Wilts, as later generations were found back at Melksham & Warminster!
I was advised to check Chilmark Parish reg. I was hoping a fellow genealogist might have access to the reg, as it is a long and painfully delayed process to get them here
