Oh you got back even further than I did - I have William Daniels 1 (I’ve had to number them all so I don’t get them muddled!) and Mary Andrews but not William’s parents, just a little about Mary’s.  No, I don’t recognise the names Showell or Spiers; I live in Churchdown and often walk up the hill where the burial ground is by St Bartholomew’s church  - I’ll see if either name is recorded on any of the gravestones there.  It does seem a huge coincidence though, you’re right.  Fascinating stuff family history 😊.
