I wonder if the 80yr old (a nice round figure!) Edward Corkill bur Mau 18300221 is Edward s/o James of Ballasloe - no will but if the 1808 will referred to him then unlikely to have much if anything to leave - there is a Jane Corkill bur Mau 18180615 with an X marked agst in transcription of reg - possibly the wife?
