Len, Just a quick note before I have a Christmas break. Thanks for the lead. Charuish is not a variant I have seen before - it looks so obvious now.

I seem to recall some time back I had come accross Edward Kerruish and Elizabeth Christian and came to the conclusion that I had a generation missing.

I will be digging that research out again. This could well be the missing piece

Once again Thanks

Regards

Shaun
