There may be a connection here with two other families descended from a John Keane & Bridget Jennings, one now in Australia and the other in both Co Roscommon & the USA. The timeframe is right for both to be descended from brothers of Edward, Patrick & Ulick. Indeed, those same names also occur amongst the Australian Keane family. They gave Tuam as their place of origin, which I note is the nearest large town to Kilconly.
The American family also descended from John Keane & Bridget Jennings of Tuam has DNA tested and proved to be related to my family some time earlier. My family lived between Tuam & Dunmore where they were tenants of the family who owned 2/3rds of Tuam. Kiltullagh parish where the USA & Co Roscommon Keanes live borders Dunmore on the north. Their (and my) DNA type also occurs amongst other Cains, Caines, Kanes & Keanes from east Galway.
