Most Parish Registers and Bishop's Transcripts for most parishes have gaps in the early years, which I have dubbed "Black Holes". All of us have ancestors whose baptisms or burials got swallowed up in one of those holes.
The earliest registers for Gwithian begin in 1560 and are remarkably complete, but there are a few missing years.
Below are the missing years. This may be helpful for those compiling early Gwithian families, where persons are known to exist from Wills or other records, but whose birth or death cannot be found. Knowing which years are not extant can often help to narrow down the time period of the missing events.
