Greg, further information from census records showed more options. - Look at the place names of where Robert Corkill & Cath Quayle were living. I have seen no proof that John Corkill and Elinor Casement were your ancestors (as I have written several times) - they are one possibility. Because of the number of same forename Corkills you need to keep an open mind and explore all the possibilities. Including wills!
