Cornelius, my grandfather, had an uncle Timothy who preceded him to Chicago and owned a grocery store on the southside, around 45th. His father was Michael Bresnahan and his mother Johanna nee Bresnahan. I haven't found his brothers and sisters yet. They were from Mt. Collins which is in Limerick. His wife was a Murphy from Castleisland, Crinne Hill, Catherine, whose mother was Mary Hickey. The family owned the hardware store in Castleisland.

Hope this helps.
