My FOYs are from Co Mayo. In the 1830's several lived in Carramore, Backs/Knockmore, according to baptism records which also show some as sponsors for one another's children. There are several different Patrick FOYs at the same time, likely all closely related. Some of the other families with them there were SYRON/SYNON, MANLEY/MUNNELLY. There are several places called "Carramore" one is sw of Ballina, one just w of Lacken, another nr Belmullet. My ancestor Patrick FOY b est 1797 m Catherine MANLEY MUNNELLY abt 1827. All but one of their children were baptized in Co Mayo, except the youngest who was b after they emigrated to Waukegan, IL, USA in 1849. Shortly before they left Ireland they were living in Ballina, south & east sides. Various misspellings incuding FAY, FARY on US census records. I have a large tree, including some in England & PA, also dna results FTDNA, dna.Ancestry, GedMatch. Would love to connect.
