McMahon, McDermott, Lappin
Does anyone researching the McMahon family from County Monaghan have a marriage of a McMahon to either/or a Lappin or McDermott? Families with those names predominated in Annies townland, Monaghan, early 1800s in various primary sources, and again in the lead mining area of Lafayette County, Wisconsin, in 1850 or thereafter. How about a Garrett or Garret connection to any of those names about that time?
