Sorry, I can't find User Submitted Trees. John Corkill's 1770 bapt appears twice in the "old" IGI: www.familysearch.org/search/collection/igi

It also (strangely) appears in "Isle of Man, Births and Baptisms 1821-1911".

But I couldn't find an entry for him in "Isle of Man, Parish Registers, 1598-1950", which seemed to be the obvious place.

What was his date of death in the IOM?

Would you please post the link either omitting the ht tp as Frances suggested, or put a space in the middle as written here.

Thanks for your messages which I will answer shortly.
