Hi David,
It's a bit of a mystery isn't it?
The LDS stuff obviously conflicts in some places and I was just trying to tie up some loose ends. It was the Richardson side of things I was primarily concerned with. It is not particularly central to my direct line, so I don't think I'll get the marriage certificate just yet (I'll add it to the ever expanding list).
Thanks for looking, I think I'll file this one for now!
Cheers Rob
