Sarah - I realise that your messages are a few years old now - so if you still look in on the boards, this is an update on
Halls in St. Ninian's
Churchyard.
The
Churchyard contains many post-1855 graves, not just pre-1855 ones.
The pre-1885 MI Book (Mitchells) lists one grave:
William
Hall & Ann
Stevenson.
There are no other details listed in the book so I presume the stone only bears the two names.
