Greg, I'm confused. Are you suggesting that the Jane Hogg who married Thomas Quayle 2nd June 1860 in Kirk German was Mary Jane Hogg who was bapt 1 Feb 1846 at Saint Mathews, Douglas?

Lillian, in May you wrote "From Tuesday I will have time to spend at the Museum so will check the Parish Reg. as you suggest for the Marriage of James & Jane, also Thomas & Mary/Margaret Kelly. Will keep you informed".
If you post that marriage information it could help with identification.
