I am a descendant of Patrick Gavin whose 2nd wife was Ellen Lynch. Patrick and his first wife (name unknown) had several sons; Patrick and Ellen had 2 sons, John and Malachi. John born in Borrisokane, Tipperary, Ireland. I have no info at this point re ancestor of Patrick. John baptized at Sts. Peter and Paul Church in Borrisokane 27 Jun 1839. Sponsors were John Gavin and Mary Gavin.
Malachi is an unusual name; perhaps uncle and nephew.
