Peter Mooney / Margaret Doyle, Rochfortbridge

Searching for information about Peter Mooney and Margaret Doyle and their families. Peter and Margaret were married Feb 1829 in Rochfortbridge. I am aware of 3 children born in Rochfortbridge - Patt b. 1832, Thomas b 1838 and Margaret b 1846. Thomas and Margaret eventually emigrated to Jefferson County, Ohio USA. My wife is descended from Thomas. Based on the gaps in the birth years of the 3 known children, I assume there are others.
 

Also, I found a Peter Mooney b July 1809 to Terence Mooney and Alice Brady in Rochfortbridge, The date and place make sense that this is the same Peter, but I have nothing that definitively confirms that. I have no additional information on Margaret Doyle. 

Any information or direction is appreciated.
