My father in laws sister married Kevin Healy and another of his sisters married a Patsy McQuillan...and my mother in laws sister married Peter McQuillan..Patsy and Peter were brothers!
So the Healys would be 1st cousins to these 2 McQuillan families and my wife.
My wife would be 1st cousins to the 2 McQuillan families..once via her father's line and once via her mother's.and 1st cousin to Healys via her father's line. Basically 3 of my wife's Aunts are involved, 2 paternal, 1 maternal line.
The 2 McQuillan families are 1st cousins too and apparently the Ballymakenny Healys connect to one of these lines.
