In the England, Cornwall Parish Registers, 1538-2010 Cornwall St Just in Penwith Baptisms, Marriages, Burials, 1599-1681 the baptisms [haven't checked many pages] are shown as borne as against baptised. A sample is attached. Is the word which looks like borne some sort of accepted abbreviation for baptised?
The image seems to contain entries dated 1657 and 1658. This was near the end of the English Commonwealth following the Civil War (1642-1660)and there were many odd rules and regulations introduced by Parliament into the conduct of church affairs and many parish registers were neglected. In this case, could it be that the incumbent had decided, or been instructed,to record date of birth and not baptisms?
