The McMahon Family of Ireland is a website devoted to the study of the genealogy and history of the McMahon Family.
Recently with the advent of reasonably priced DNA testing genealogists now have a wondrous tool at their disposal to go along with documented family histories. Although many view this as a threat to their long held beliefs of who and where their family belong, I take the opposite approach and want to know the truth about my forebears. Brickwalls are crumbling with affordable DNA testing and the future is very bright with each new advance in genetic genealogy.
There are two unrelated origins for McMahons in Ireland. The McMahons of Thomond, present day County Clare, descend from Brian Boru while the McMahons of Oriel , present day County Monaghan, descend from the Three Collas . It is my desire to collect and share information from each sept.
