History of Mary Nasson

We needed a tool to lift out the clue at Mary Nasson's grave. 
It read:

"Half I gave to Moulton
the only soul I trust."

We each roamed the gravestones
in search of Moulton. 
Once we located his memorial stone, we scoured it for a clue
and found:

"Go see my friend Rollins at holy Trinity for the final piece."

Next stop: Holy Trinity Church, York.
