Thanks for your reply, Dick. I am writing from Sydney, Australia.
When I looked at this will I was actually looking for the family of another Joney Sayle, but I thought the relationships might help someone researching that family.
The Joney Sayle whose family I hoped to find married John RADCLIFF in 1759 in Andreas, and died in 1771. The 'uncles' supervisors of her children were Philip Sayle, Thomas Sayle, and John Teare. A John TEARE married Margaret Sayle in 1761 [Andreas].
I think this was probably the family of Philip SAYLE and Ann CRAINE who married in Andreas in 1725 [Joney bap.29 June 1733 Andreas].

Does anyone have any information about this family and/or their descendants?

Thanks again,
Sue
