Does the date surprise you?.
I think it quite a sad tale, myself.
There seems to have been some determination to obtain a conviction - any conviction. Methinks, if the 1735 Witchcraft Act, they might well have tried for a crime such as “being in possession of a loud shirt within the hours of darkness”.
(btw - the “loud shirt” bit is from an old TV comedy series - possibly “Alas, Smith and Jones”)
