My grandmother was Katherine Ryan of Kiltyclogher, Leitrim Ireland. This is a modern form previously rynn possibly wrynn. She had a number of sisters who married and moved away losing contact. She was born around 1890 and lived in Rathfriland where she raised her family. Had friends in USA but I have no details. There are references to Wrynns in Kiltyclogher in Leitrim, in the church and town statue to civil war fallen. A relative of my grandmother was Sean Mc dermott, a signatory to the border treaty. I recommend you contact the museum to him and or local priest, both Kiltyclogher. Good luck and hope to hear from you.
