Hi Sylvia: Sorry, but none of the John Skillicorn's appear to match any of mine as the other names you mention don't mean anything to my tree - at least so far, but you never know as research continues.

The John Skillicorn's I have in my tree is a JS DOB 1798 married Isabella Cowley DOB 1804: The next JS DOB 1839 (son of the above JS) married Jane Moore: then Eliza McKeone (nee Cowin) after Jane died in 1875: The next JS DOB 1863 (son of the above) married Eliza Catherine Kelly.

Good luck with your searches!
