Related Surname Info: I am searching for relatives of John J Beirne (1810-1866) who probably lived in the area near Culleenirwan and Culleennoulagh. He married Mary McDonnell (1828-1905), who was the daughter of Thomas McDonnell and Margaret Downey from that area. John had 3 daughters and 4 sons, including Thomas (1857-1905), who moved to SFO and married a Roscommon native Mary Mee (my great grandparents).
Any information or hints will be appreciated.
