Eileen,

There is a tree on Ancestry that suggest that Patrick died in January 1884 in Ballykerogue, Kilrossanty, Waterford, Ireland at age 64. I found the death record on Irishgenealogy (free website).

In 1851, there were Powers living in Ballykeroge, as shown in Griffith's Valuation:

Note there's an Anastasia Power listed in Griffith's.  It's of interest that Patrick had a daughter Anastasia; perhaps the one in Griffith's was his mother?

In 1820 in the Tithe Applotment Books there were Powers living in  Ballykerogue:
