Welcome James1066, every possibility you could be right, which would be great news.Church records are the most hopeful source as you will find. Three Francis entries below
Moneydorragh Upper 0r Moneydorragh More Upper I think is the townland above Moneydorragh More ie includes mountain tops. when you look up the printed book version for townland Moneydorragh More in Griffiths valuation the list starts with map references

13 acres and a modest house valued at ten shillings pa
