I am seeking some information on my McGuckin ancestors. My mother's family name is McGuckin. She is descended from a John McGuckin who was born in Drogheda Ireland in the early 1850s. He settled in Cork city in the 1870s were he worked as a mercantile marine engineer and died there in 1908. His father was a Timothy McGuckin also an Engineer who was still living in 1875. It is this Timothy McGuckin that I am looking for genealogical information on. Family lore indicates that he was originally from Scotland and a Presbyterian. Has any McGuckin in Scotland or Ireland got genealogical data about him?
