Thanks to all of you for all the extra data and documents. I'll be going through these in the coming days.
Capetown, I'm afraid Scholastica and Frances cannot be the same person, as we have a baptism certificate where they both appear as different daughters born of the same mother (Rachel/Rachael Coxhead) - see below.
And yes we have the marriage of William Seville and Scholastica Hopkins in Wiltshire, 1745 -thanks for the confirmation and extra information, hanes teulu !
Yes, Scholastica Hopkins appears to be the grandmother of the William Seville I was originally looking for. The tricky bit is there were a whole bunch of William Sevill(e)s before him, so I'm trying to sort those out.
For the moment, I have temporarily added these ancestors to my family tree, so I'm going through all the records to make sure I've got this right (see attached).
Scholastica was indeed a very rare name, but we have several of these going up the tree (see picture below), the most ancient one being Scholastica DAY, who died in 1748 in Swindon, Wiltshire. I'm still trying to find her own ancestors to see where this tradition of naming girls Scholastica came from.
Still no clue about Frances Chalestifor though, looks like that one will remain a mystery !
Let me know if you have any other ideas. And thanks again for all the brilliant discoveries !
Good evening,
Niki
