I posted this in talk because I didn't know this board existed
so thought I'd post it here too.
I thought this could be interesting, unless I'm the only one!
My granddad is descended from a very important French noble couple, his ancestor took on their title as a surname (like William Wales, Andrew York etc) this woman was the only one to ever hold this title. But history records them as childless. What we know is that they had a little boy who was secretly sent to the UK to protect him from the issues of the time.
Sadly it's my Mum's dad so I don't have a cool name my own family name is a rather boring typical British name, although my married name will be a German noble name (not so secret though) so can't complain too much
So, does anyone else have a cool "history doesn't know this" story?
