Ann KINRADE aged 75, Ballacrink, was buried in Maughold on Apr 18 1871.
This looks like the Ann Creech bapt 31 January 1796 who married William Kinrade/Kinread.
Brian, did you find the family in censuses? Last child bapt Maughold Dec.1839. I looked in the Maughold 1841 census to see whether they were living near the Corkills, but not found. Also, Ann not found in 1861.
