Re.Rose McCarthy(1816)first wife of Hugh.
Maiden name Hoy/Hey? ( Brian Lawson's dissenter births Rose McCarthy 22/10/1842)

Hugh,Bridget McCarthy neice/uncle? brother/sister? In my limited experience of family research it's not been uncommon to find first born son named after paternal grandfather.Thus I opted for sibling relationship.
