I am also looking for information about the Broderick family from Athenry. My great great grandfather was Michael Broderick, who was married to Margaret Joyce (b. 1840). Margaret Joyce's parents were Patrick and Bridget Joyce of Athenry. I am wondering if there is any connection.
I know Michael Broderick had a son named Mchael who emigrated to the US around 1891. His other children were Jane, who married John McGrath and emigrated in 1891, Patrick - who remained in Ireland, Delia Mary, Mary - emigrated in the 1890's and married George Edward Duffy, Margaret and John Joyce - who married Marjorie Kelly in 1909.
If anyone knows anything about ascenstors of Michael Broderick, or his wife, Margaret Joyce Broderick - I would appreciate it.
