Thanks for this Arthur. I have now had a look at these transcripts of the registers made in 1887 and 1907. The latter seems more complete but the registers are damaged so there are entries missing or unreadable.
However I ave been able to find out the following that I thought I would share here for any other future researchers to find.
Looking at the records it seems that a William Kynge married in Marton in 1561. They had one child in 1566 whose name is lost and potentially others as the records are damaged. William Kynge of West Marton was buried in 1571 and as an Alice Kynge widow of West Marton was buried in 1604 I assume this was his wife.
A Henry King is in the records from 1599 to 1617 and appears to have had three wives. His first wife Isabel was buried in 1599, his second wife whose name is lost was buried in 1617 and his third wife Isabel Slater (who he married in 1617) was buried in 1619.
With his second wife Henry had an infant buried in 1601, William King in 1602, Henry King in 1604, twins James and Alice in 1606 (I have now learnt thanks to their baptism that 'gemelli' is Latin for twins) and a son whose name is lost in 1608.
As Henry named a daughter Alice and given the location I assume that Henry was the son of William and Alice King - perhaps the child with the lost name baptised in 1566.
After these entries the only other King I have found in the records is that of a Jane King daughter of Henry King in 1644. This ties in with the three baptisms in Skipton born to Henery Kynge in John in 1647, Henry in 1649 and William in 1650. His residence is recorded as Embsay.
It therefore seems possible that the Henry King who I believe is my ancestor and who had children in Craven in the 1640s and 1650s is perhaps the Henry King baptised in Marton in Craven in 1604.
Henry King was in Marton in 1644, then was in Embsay from 1647-1650 before ending up back in Mire House in Marton where he resided at the time of his death in 1680.
However after this 1644 baptism for Jane there are no more King references in the 1600s registers of Marton at all so it doesn't shed any more light on when my Henry converted to Quarkerism. What I really need to try and do is find more references to him somewhere.
I now need to see the parish registers for the 1600s for the nearby Broughton, Thornton, Gisburn to see if there is any trace of Henry King there.
Thanks again for all for your replies.
Kind regards,
Jon
