Mulligan, Bourke, Gallagher

Looking for any info about the Mulligan family. Patrick Mulligan Sr andwife Bridget Gallagher,and son Patrick and wife Mary Ellen Bourke (Burke), all baptized and married in Agher.I have recently found through DNA, a fourth cousin, grandparents names were Dixon and Moore. Shestill lives in the area of Summerhill/Agher, but knows nothing about her family history. Patrick and Mary Ellen left Ireland 1853 to Ballarat Australia. I have most all the family history, just looking for any relatives in the area and possibly where their home was located.
