Hi Jane,
John Kenna and Margaret Fayle were my paternal ggg-grandparents.
My gg-grandmother, Charlotte Eleanor Kewney (spelling) was the older sister, chr. 10 June 1810, Lezayre, IOM, of your James Kenna, chr. 11 Oct. 1812, St., George, Douglas , IOM.
There are more postings about this in the section just higher up on this page.
I am new to genealogy searching and have been searching for my Charlotte for a long, long time. With the help of Sue and David, we finally found her yesterday.
Kindest regards.
Penny
