The Mullin Family

Fortunately, somebody associated with the Mullin line had visited Ireland decades ago and had done some research that I have access to. Here is what I believe is my Irish genealogy to my great, great, great, great, great grandfather Michael Mullin, born in middle of 18th century. The copy of typewritten page (before computers) of Mullin information indicates that Michael Mullin was forced south to Woodford, County Galway by Oliver Cromwell. But forced south from where?And looking at map of Woodford, did grandpa stop going south simply because of Shannon River? Michael Mullin (1745-1820) married Mary Bonful (1747-1817). Their son Richard Mullin (1787-1847) married Celia McDermott (1789-1869). Their son Michael Mullin (1824-1908) married Margaret Mahon (1824-1906). Their son Patrick John Mullin (1856-1951) married Mary Jane Lodge (1866-1895). Except for Mary Lodge, everybody from Ireland, likely Rockhill, Woodford, Galway. Note that from Michael Mullin, oldest sons were alternately named Richard, then Michael again, then Richard again. Regarding Mary Lodge, I now understand that her parents, Charles Lodge and Ellen Doyle, were supposedly born in Ireland. And if this is the case, then my mother's geneology is possibly all Irish, although I never met any Irish-born grandparents. Also, Rockhill enters the picture, said to be north of Woodford. Is Rockhill another village? Records commented about dimensions of stone walls in Rockhill. 3 feet wide X 12 feet tall, for example. I don't know significance of that info. Finally, the Mahon name, associated with my great grandmother, actually turned up in a Google search of "Rockhill Woodford County Galway." Noticed modern houses in associated pictures. Quite a contrast to farmhouse in background of copy of b&w Mullin family picture. Thanks for listening.
