They now have 4 sets of vital records for the Isle of Man though there's a warning for the first 3 collections that only a few localities are included and the time period varies by locality.
- Isle of Man Births and Baptisms, 1821-1911
- Isle of Man Marriages, 1849–1911
- Isle of Man Deaths and Burials, 1844-1911
- Isle of Man, Parish Registers, 1598-1950, containing baptisms, marriages, and deaths.
There's also a full list of all 891 of the Family Search collections.
The family member I found was Hamlet Lowe who married Catharine Ware at Braddan, Isle of Man, on 08 Jan 1788, though, of course, I still need to check that he is the correct one. I wonder where she was born, as there's no mention of her birth in the Isle of Man.
