Hi there,
You appear to have a choice of two -these are from the BVRI2
John Milham bapt 3 Aug 1787 Ewhurst parents James & Mary
John Milham bapt 12 Oct 1794 Ewhurst parents John & Hester
But searching a little more, there are also the following entries:
(boy) Millham bapt 28 Oct 1791 parents James & Hester
Thomas Milham bapt 24 Jan 1793 parents James & Hester
James Milham bapt 20 Jun 1802 parents James & Hester
William Millham bapt 18 Jun 1809 parent James & Esther
I think there may be a mistake in the transcript for the 1794 entry and it would be worth checking the original.
These are the marriages:
Ewhurst, East Sussex, 15 Jan 1787:
James MILHAM m Esther SERGEANT
Udimore, East Sussex, 10 Feb 1787:
James MILLHAM, Widr Northiam m Mary BURGESS, otp (B)
Hope this helps you.
Nell
