Neville of Parish "Recail"

I am trying to determine if a Bridget Comfet Neville who died in 1884 in Ottawa, Canada is my great-great-grandmother.

Family lore says Bridget Conroy married Thomas Neville somewhere in County Limerick. At least 2 of their children were born there (Andrew about 1841 and Bridget about 1842). We believe they emigrated to Ottawa and know their children lived there.

I located a photo of the attached headstone from a Catholic cemetery in Ottawa, very near where Andrew and Bridget were known to have married. I am trying to determine if this is the gravesite of Bridget Conroy.

Over the years, I have uncovered several spellings of Bridget's last name - however, Comfet was totally new. It appears that Parish Recail was a variation of Rathkeale. Since the Limerick location matches family lore, I am exploring this woman and her previously deceased husband, Thomas Neville.  (Note: I was unable to locate any information about Thomas in Ottawa; this may indicate Bridget emigrated with her children after her husband died in Ireland or he may have died outside the Ottawa area.)

Thanks for whatever information you can provide.
