My great grandfather, Joseph Foley (Folan) settled in Pittsburgh PA 1895 or so. married Anne Connelly (bIRE 1872) 1899. Joseph's father was Michael Folan his mother was Barbara Green. Family search records indicate he had a sister Barbara b.1870 Roundstone and a brother Michael b. 1866 Roundstone to the same parents. It seems that the Roundstone area was rich with Folan and Green families which intermarried frequently.
Any help in providing more info on the Folan/ Green families would be greatly appreciated.
