I thin k you're right Trish it will remain a mystery unless the right Parish PRs become available.
I think there is a jinx on that family line.
My ancestor Richard Pamplyn (later Pamphilon) married Joane Woodley 2 Mar 1638 at Childerditch, Essex by licence, found Joan but Richard will be a mystery too, they had five known children all it appears at Widdington between 1638 and 1665, unfortunately the are no Widdington PR records prior to 1666. The family moved between Widdington and Rickling quite a bit and Rickling baptisms start at 1662, so if any of the five children were baptised at either parish there's no hope of finding them.
The way I found out of their existence was from the will of Richard's brother Nicholas which bequeathed some cash to the children who were noted as being the children of this brother Richard.
One of Richard's daughters Sarah Pamphilon married my ancestor Thomas Smith at Widdington, originally, trying to find Sarah Pamphilon's none existing baptism was a hair tearing out exercise.
The 1638 Childerditch? marriage of Richard Pamplyn aka Pamphilon was another mystery until the Marriage Licence Allegation came to light which stipulated St Faith, the only church I could find in Essex with a dedication to St Faith was at Childerditch, once again PRs were a pain, Free Reg Childerditch marriages start at 1750 and I cannot find the marriage in Ancestry.
So, Jinxed they are.
