Hi, looking at parish registers, I could find no marriage for James Lovett to either Elizabeth Ayres nor Ann Malaughney. I found 2 births for Elizabeth Ayre/Eyres one in 1805 co Antrim and one 1804 co Dublin but none in county Kilkenny. As to Ann Malaugney, I found 23 between 1811-1831 although the name is coming up as Mullowny/Moloney which to me seems a bit off. The spelling issue could make her birth hard to trace.
I then looked at the Tithe Applotment Books 1814-1855 and came up with the following Ayers in co Kilkenny. David Aher 1823 Castlecomer, John Eyre 1827 Clomantagh, Richard Eyre 1833 Muckalee & a ----- Eyre in 1826 Freshford. One of these may be Elizabeth's father. Hope something is useful, Kim
