John Duffy and his brothers Bernard and Patrick, 1873

I am looking for birth records for these three brothers to confirm that they are from the parish of Mullahorn (sic--as given in the Missing Connection item quoted below) in County Cavan, as suggested by a Missing Connections post of 8 Nov 1873.in the Boston (USA) Pilot.

The brothers were living in St. Louis, Missouri, USA, in 1870. Their parents were John Duffy and Cecilia Daly. Their cousin Patrick Duffy lived in Waltham, Massachusetts in November 1873.
