I've been researching a Rose Quigley who married a Patrick O'Malley in the same parish as your Peter: Aughaval/Oughaval - 3 Oct 1836 - witnesses: Hugh O'Maly and Bess(?) Quigley - do you know if Peter had siblings and Patrick being one of them? I believe Patrick & Rose moved to Scotland before 1860. She died in 1884 in Govan, Lanarkshire, Scotland.
