Looking for info on Morgan BYRNE and wife Margaret HENNESSY of Castle Roe, County Kildare. My records indicate that they were married May 30, 1812. Margaret died in the 1840s or 1850s. My info says she was buried in Dunmanogue Cemetery in County Kildare. Is there such a cemetery, and if so, is there any index or gravestone transcription? Any help will be appreciated.
