Hi Gilld
I'm descended from John EMMINS who married Beatrice PASK in Burrough Green on 8 March 1726/27. My ancestor was their daughter, Mary, but they had two sons - John, baptised 6 March 1731/32 and William, baptised 27 Oct 1734, both in Burrough Green. It may be that one of them was the ancestor of your Johns? Do let me know if you manage to trace your line any further back.
Regards
Ruth
