I have a line of family that has a Patrick Joseph McGrath (sometimes called Joseph P) who married Margaret Ormond. Patrick was born in Ireland, Margaret in Nova Scotia. Their ages are not known at this time. After marriage, they moved to the Boston Area (Hyde Park, Suffolk, MA, USA). They had 3 children:
1. William McGrath (b. about 1860, per 1910 US Fed Census in Hyde Park), immigrated to USA in 1893. He does not appear to have been married and no children.
2. James Francis McGrath (b. Aug 1863 in Clashmore, Waterford, Ireland; died Aft 1915 (unknown)) - married a Margaret Sarah Durant. Have 7 children while living in Hyde Park.
3. Patrick Joseph McGrath (b. 10 Feb 1868 in Clashmore) - married 1st, Jane Murray (no children), and 2nd Agnes Agatha Manuel. They had 2 children in Hyde Park (Robert died at 1 day old, Helen born in 1915). He most likely died in Miami, FL (his 1920 US Fed Census have them there).
