Hi G.B. and welcome to RootsChat.

It's good to get a reply after all this time! I am aware of the Lavendon Faireys, though I haven't been able to link them to my Hunts family. The interesting thing for me was that so many of the Hardingstone Faireys shared first names with mine, and I wondered if the two families were connected.
We do actually have a Zilpah/Zilfer, etc. Fairey in our family, too. She was born in Ellington, Hunts, in 1861, the daughter of William & Ann, and was the granddaughter of my gt-gt-grandfather's older brother. She emigrated to Australia, where she married, had a daughter and died fairly soon afterwards.
I would be interested to see your baptism list, if possible, just to see if I can make any link. I'll send you a PM with my email address for a reply.
Regards
Gillg
