Langans Baptized at Kill

Patrick Langan and Catherine (Kate) Boyle had 7 children baptized in Kill.  My ancestor, John Boyle Langan, was born 1832 and emigrated to Pittsburgh, Pennsylvania.   The family lived in Bonmahon, co Waterford.  Patrick Langan was born in Dublin and his father was Peter Langan.  I have been unable to verify this.  He had a brother, Peter, who was buried in Kill graveyard, the last row in the upper section, behind the original sacristy.  Patrick died in 1877 and was listed as a shopkeeper.  Catherine died also in 1877.  I visited Bonmahon and Kill and found them beautiful.  I would love to connect with any Langans, Boyles, or Flynns.
