Do you have new information re the Wanes to share? I have been doing some research into the English Wanes, my gr grandfather's siblings in particular. I found some lovely pics and info on Red Barn Farm which now apparently operates as a Bed and Breakfast and equestrian centre.
If you are located in UK ATM you might want to visit there. By all reports it is very well run by the new owners.
I also found information relating to Vinehall in Sussex. I was told it was originally built by Marian Elkington's father, Henry Tilden Smith, but I believe it was actually built by his brother? , Tilden Smith. The probate mentions all Tilden Smith's children including Mary Anne, but the man recorded as her husband isn't John Elkington.
