Hi
Unfortunatly there is no name index at the moment for that area of Macc, I have had a look in the Waters and Commercial road but no sign of him, sorry.
I did find a marriage of a William Gallimore and a Susanna Bennison at St Peters Prestbury 3/April/1820.
Looks like he may have married back into the same family.
Goog luck
