Thanks for your reply. Sounds like you have done a lot of work & it would be great to see it published!

The 3 x "John James Boydes" I have are...

1) b 1850, Ballaugh, son of James Boyde & Jane Corlett
2) b 1859, Ballaugh, son of Philip Boyde & Catherine Corlett
3) b 1888, Ramsey, son of William Thomas Boyde & Martha Louise Quayle

Additionally I have the following 5 x "John Boydes", (although have not yet confirmed the sources)...

4) b 1782 son of Philip Boyde & Jane Cowley
5) b 1782, Ballaugh, son of Daniel Boyde & Ann Cowin
6) b 1793, Ballaugh, son of Thomas? (or John?) Boddagh & Elizabeth Cain
7) b 1807, son of John Boyde (b1782) & Margaret Cannell
8) b 1819, son of John Boyde (b1793) & Isabella? (or Elizabeth?) Howland

Do you have these? Do you know who are the parents of the John Boyde (b1782) who married Margaret Cannell?
I suspect he is the son of either "Philip Boyde & Jane Cowley", or "Daniel Boyde & Ann Cowin".
