Congratulations Gadget!
(Though I don't really know why I say that - it's not as though it's an achievement on your part

I suppose it's more like winning the genealogical lottery.)
A recent series on ITV Wales tried, not totally successfully, to trace a family tree in reverse, starting with a celeb and trying to trace their descendants. It had even more of a feeling of a "fix" than WDYTYA has occasionally, where you realise the researchers knew who they were going to end up with before they started.
But the first traced the line of Owain Glyndwr down to Monmouth MP David Davies, ironically a rather anti-Nationalist Tory, and his father had some fantastic pedigree books, which made good TV, even if it did make it obvious that the programme-makers had known about the link in advance. Perhaps you and DD are related too.
