Cornelius farmed in Kilbaha, Newtownsandes (Moyvane). He appears to be the father of my known ancestor John Shanahan based on the fact that I have been DNA-matched by Ancestry with a number of Cornelius's great-great-great-grandchildren, the type of match suggesting the above connection. However, because this is not 100% certain, I have added a caution.
There are other Shanahan families with Kilbaha connections but I have been unable to determine if they are related to Cornelius or myself: a Margaret Shanahan married a Daniel Connell around 1830 and lived in Kilbaha. They had at least four children: Patrick (born 1831), Johanna (1834), Daniel (1837) and Mary (1842). Then there is an Ellen Shanahan who married a Henry Langan and who had at least two children born in Kilbaha: Mary, born in 1819, and Patrick, in 1823. A Sarah Shanahan, married to a Redmond Langan, had a son named Denis, born in Kilbaha in 1828; and a Mary Shanahan, married to a Thomas Sperane, had at least two children: John, born in Kilbaha 1813, and Thomas, born in 1815, also in Kilbaha. There was a Johanna Shanahan, married to a James Carrig and living in Kilbaha, who had a son named James who was born in 1838. There were two Thomas Shanahans, one who married Brigid Sheehan and who had a daughter name Jane in 1838, and the other who married Brigid Nolan and had a daughter named Mary in 1862. However, we have no evidence to connect these families to ours.
In the course of my research I have also come across references to a Presentation brother named Edmund Shanahan who was born in Kilbaha in 1841. However, it appears he was actually born in Listowel, Co. Kerry, so there is probably no connection to my family, but just in case he is related to me, here is the information I have found on him:
Edmund's parents were Edmund Shanahan and Ellen Stack. Edmund junior entered the Presentation novitiate at the South Monastery in Cork in 1860, taking Austin as his name in religion. Br. Austin became principal teacher in the South Monastery and in 1871 he was elected Superior of that school. From 1871 to 1874 he was very involved in the building of St. Joseph's Industrial School in Greenmount in Cork, and later, in 1880, he took charge of St. Vincent's School in Dartford, Kent, turning round its fortunes. Returning to Cork in 1882, he was once again elected Superior of the South Monastery. In 1889 Br. Austin was elected one of the four Assistants to the first Superior General of the Presentation order. In the late 1880s and early 1890s he travelled extensively in the United States, Australia and New Zealand collecting money to build a new novitiate at Mount St. Joseph in Cork. Br. Austin died on 24 October 1902 and is buried in the vault in the South Monastery.
The Shanahan surname is common throughout Munster and the south-east. The Shanahans were a sept of Thomond, an area which covered much of north Munster, but in 1318 they were expelled from the Sixmilebridge area of Co. Clare by Turlough O'Brien and the McNamaras. They were scattered throughout Munster, especially in counties Limerick, Cork and Waterford.
