Mike B,
Finding the exact location of where kin lived in the Bansha area is something I have been dealing with for the last 14 years. My gg grandfather, John W. Butler and his wife Margaret Elizabeth Buckley were married in the church at Bansha. They had 5 girls that were baptiized at the same church, with the last child Bridget born and baptized in 1851. In 1853 and 1854 they left Ireland and came to the USA. Bridget the youngest did not come to the USA with them and apparently died in Ireland or on the crossing by ship. I can find no record of her being buried in the cemetery by the church in Bansha.
As to the McCarthy surname I know very little about Catharine McCarthy who married Patrick Beatty. Catharine is my gg grandmother. I know that Patrick was from County Mayo, but I have no information on where Catharine came from in Ireland. Catherine and Patrick had 4 children. Mary, the first born married my great Grandfather James Joseph Butler, The 2nd and third born bacame Catholic Nuns in Indiana, and taught school in Indiana, and both are buried in the convent cemetery in Terre Haute, Indiana. The 4th daughter entered the convent, but dropped out and returned to Richmond, Indiana and lived in that are the rest of her life. My great grandmother Mary had two children, my grandfather John Clare Butler, and his sister Pearl Clementine Butler. I know very little about Catharine McCarthy or where she was born in Ireland. I guess maybe she was from County Mayo as her husband was from that county as that shows on his citizenship papers. Sorry I can't help with that info you are looking for.

Irish blessing to you and yours,
Bernie Butler, Jr.
