Hi Sean: Have we been in contact in the past by chance? I have done a lot of family history research on Patrick McEvoy and Mary Rice - Renous, NB, Canada. I can trace a Patrick McAvoy to Ballybricken, Waterford City, Ireland born 1808. The family folklore from older relatives was that the we lived near the Dungarvon River in Ireland and that's why the river in Renous was named that. The Dungarvon river is between Cork and Waterford.
If you think we have a match - drop me an email with your research highlights.
