Marriage records of that period probably won't list that info. The ones I've seen usually only tell you if person was "of age" and previous marital state, i.e. widow, etc.

Is this your Margaret?
Maughold MI
GH7 Sacred to the memory of Margaret Lace the beloved wife of John Lace of the town of Ramsey who departed this life 6th Decbr 1841 aged 59 years
Dear children forbear to mourn and weep
Whilst sweetly in the sudt I sleep
I left this toilsome world behind
A crown of light far to find

Regards,
Donna
