Eleanor Callow and John Caveen

I'm trying to find out details of Eleanor Callow and her husband John Caveen - and more specifically WHO JOHN'S PARENTS WERE - as being the parents of Frances Amelia Caveen, born in 1860 in Braddan and who married James Cope 4 Oct 1879.
I have a number of Caveen's on my tree but this is a branch I knew nothing about.
