If born circa 1776/7...
Foulden is next door to Northwold, so a possibility might be the John baptized there 13 July 1777 to William and Elizabeth Reeve?
(possibly they are the William Reve and Elizabeth Sharwood who married 15 Jan 1771, same place?)
PR here with that baptism

Thanks jonw65. Try as I might, I cannot find the index to this marriage, nor the child John of Foulden, in spite of the parish record you attached.
Someone else asked why did I pick the John Reeve of Little Fransham that was born/baptised on 6th October 1782, in spite of him being 3 years younger than Mary Towler. The reason is that all the others died, and the one suggested from Foulden of 1771 (above) cannot be found by myself.
Process of elimination was followed.
I think I probably need to close this post as we are now onto another John Reeve and his forebears.
I thank everyone for their help. I'll take advice and use Family Search and Free Reg. Bewteen them I should be able to get some idea of what is going on.
Regards to all
