The only death I see that's close by date and geographically is this one - in 1868 :
Name: Patrick Lennan
Event type: Death
Year: 1868
Registration district: Baltinglass
Age : 68 (est. birth year 1800)
Volume: 17 / Page : 280
Baltinglass town, where the district is based, is to the north east of Carlow town and about 20km.
Do you believe this Patrick is an ancestor ?
