Hi Kathleen

I don't know if this is any use
Edith Annie Cooil, widow d/o Thomas Mason Kelly married Thomas Edward Beckinsale, batchelor, s/o Thomas Edward B at Malew, 3 Sept 1949. (Ancestry)
No report in the Manx papers that I can see.

28 Dec 1946 obituary of William h/o Edith Cooil at 21 Queen St, Castletown. Buried Malew 31 Dec 1946. (Suddenly)

May not be your Edith

Mona's Herald 11 May 1943 mentions Geoffrey Cooil, & also an Audrey Cooil involved in the Methodist Sunday School anniversary

Karen (nee Cooil)
