Thomas and Ellen Silke were brother and sister from Auclogeen in Annaghdown parish, which is my parish. It's about half way between Tuam and Galway, about three miles from Claregalway in Co. Galway. Thomas married Honor Hannon (Hanen). Their son Thomas married Bridget Ford and Julia Collins. Ellen married John Creaven. Bridget Silke, another sister, married Martin Hession, my great great grandparents. Another sister, Margaret Silke married Patrick Fahy and another sister Judith/Julia married James Kilkelly, now Kelly. No Silkes left in Auclogeen but all the other families are within a few miles of it, including mine. Have put a lot of research into it. The three men you mention were all first cousins and John Hession, my great granduncle, is said to have married a Burke woman, my great great grand aunt on my grandmother's side. Would love to hear more on the families in America as would the Creavens and Fahys.
