I also heard the reference to Patrick McManamon who arrived in Shrahmore Co. Mayo in 1801 from Donegal. ( He was my GGGF)
He married a Doherty and they had 4 children (Pat, Frank Mor
who married Honor Rowland, Michael and Julia who married Thos. Chambers).
Frank Mor and Barbara Rowland had 6 children(Pat, John Peter, Neal Kate & Frank Honor) one of whom- Pat (my GF married Winifred Dyra and they lived at Shean Lodge, Ballycroy)
