Date Of Execution: 2 May 1720
Execution Place: unknown
In Beaumaris Gaol the following information on Anglesey executions appears as an exhibit:
Tu 2 May 1720 Sian, daughter of Evan of Llandaniel for robbery
I do not know the source of this information. It appears to bear out five of the six potential hangings between 1735 and 1804 though with discrepancies in the names and crimes.
