Thanks so much for your reply Ginny.
What I know about my Bresnahans (Brosnahans) in Cork is that they come from a town called Boherbue. Another relative whose mother made the trip over said that the church and all of the records burned.
John Bresnahan, son of Maurice came to the U.S. with his two brothers Timothy and Tom when he was 18 years old. John went to work on the Pennsylvania RR laying track. Brother Tom disappeared shortly after arrival and was never heard from again.
John and wife Mary (Toomey) lived at 1219 Barr St., in Ft. Wayne in the early 1900's.
