Heraldry in Fahan & Buncrana Co Donegal

A visit to Buncrana Church of Ireland and Fahan old graveyard turned up a few interesting heraldic items. A seventeenth century gravestone of James Dow(---?) and his wife Jenet Brown is interesting though the last three letters in the surname are not as yet clarified and the arms of a lion rampant and three fleurs-de-lis have not shed any additional light. Any insights would be welcome. The full details are below.

The coat of arms depicts a lion rampant and three fleurs-de-lis. The family bearing these arms has not been identified.
