I have these two families that intermarried but I do not know wher they went in the country. Cloonans went to Ca ME and MA but may have been here too. I only have an old family chart with many names. The main branch start with Anne Caufield and Thomas Cloonan in Galway Ireland. Their daughter Winnie Cloonan McGann died in 1916 at age 104. That is my main date.
I don't know if you have Irish family, but many Irish from galway would say that they are from Cork, becaused that is where they got the boat, but were actually from elsewhere.
