Trying to Find Mary Pengelly That Married William Scawn 1747 Launceston Cornwall

Dear Members, Can anyone help? There are no less than 120 search results for 'Mary PENGELLY' all spelling variations, but no mention of a marriage. Mary SCAWN nee PENGELLY would have been my Mother-in-law's 6g grandmother. Phew.

I'm especially interested to see if a date of birth/location can be sourced, plus her parent's names would be absolutely fantastic.

Thanks,
Alison QLD Australia.
