guess you have probable parents of edward - Matthias cain + Elinor Lewin married Onchan 18020504 - edward their 1st child - suspect Matthias was bapt Onchan 17780228 s/o john cain + mary christian (of ballachrink in reg) - Mattias was I think bur Onchan 18530412 age 75 and elinor bur Onchan 18540219 age 84 - in both 1841 (a weaver) and 1851 (carman - ie owner of a horse cab) at cronk mona (or cronk ne mona)
There appears to a will for Matthias which would confirm my guesses - there is a will for John (summarised on Manxnotebook - d 10 oct 1789;ballachrink;wife mary;son philip,john,mathias (2 youngest to be sent to a trade);dau mary,isabel

the ballachrink connection would I think make possible to track further back but 1st confirm my guess
