This is the Eric who was so good to me as a boy. I visited him in London at least twice and we exchanged some letters in French. I remember his club as making the most God-awful gin and tonic, with only a smell of tonic, and the dinner was mediocre. However, he was as kind as could be. He was the one who originally sent me a the copy of the Burke entry on the Grahams of Edmond Castle 
. I still have that copy. He had a lot of family heirlooms; paintings, letters, a huge amethyst. He died when we were in Ann Arbor, so around 1998 or so, leaving us, and each of my siblings, a pile of cash.
My sister Catherine is famous in family history because of Uncle Eric. When we visited them en masse, in London when I was about 10 (1972 or so), Catherine and the other two youngest children were given tea and cakes at a separate table. Catherine farted loudly, all the children collapsed in giggles, and Mum and Dad were highly embarrassed. Farting is something a young lady shouldn’t do, but I guess Cathy didn’t know that. I’m quite sure she still doesn’t.
Eric and Sylvie had no children.
I found his middle name on the conveyancing deeds for the sale of Edmond Castle.
