Thanks Frances.
I had cut & pasted an extract from a file I made a long time ago and hadn't checked to see if the ref was still current.

I didn't know there was a gap in the Lezayre burial records, but I've now looked at your Parish Records page which, as to be expected, was very interesting. In my records I have noted bigger gaps in the Michael registers, however - Bapts 1620-25, marriages 1629-1665 and burials 1654-1663, as well as 1621 & 1622.

The John Corlett/Isabel Kneale families are hard to unravel, though, with only the one will to go on so far.
