I have been going down the lines from Longcroft-Harfy and hope I have tracked down more of the variations in transcription. Surely one of the hardest names I have come across for spelling variations.
I have also found more about Mary Harfy's line and a fascinating link back to aprox 1600. I have uploaded the national archives refs where available.
I also spotted the wonderful YouTube video posted by Joyce's brother.

my tree is Sutton Rapkin Werret and public... and Joyce - we are something like 7th cousin 1x removed.

All the best
