There's a possible listing for George in the ecclesiastical listings for the Established Church in Thom's directory of 1848 :
George Ross incumbent, parish of Killinick, Post town Wexford, Diocese of Ferns
no sign of Henry, but there are 3 other Ross entries all under the Derry Diocese.
Killinick seems to be both a town and a civil/CofI parish and is just to the west of Rosslare town.
