It was The Gideons. You may have found my notes online (as Steve did!) though

Steve it was great to meet you too and sorry I couldn't stay long. The article is very helpful, I'd never have known about the niece otherwise, as she doesn't share their surname.
I want to dig for her info myself for a while, as I'm really enjoying the process of all of this. I'll ask for a hand if I get stuck though!
I'm going to add some of the article here later, in case it can help anyone else.
