My Tierney and Mulqueeney families lived in Kilfenora parish, townland Lickeen East, in County Clare. There are many named Ellen and James in the family. My father, James Joseph Tierney, was born in 1869 and came to the US in 1881 with his mother, Ann Mulqueeney Tierney, and brothers Peter and Patrick. Peter became a priest, served in Coffeyville, Kansas from 1901 until his death in 1921.He ws a mover and shaker and a huge rose memorial window in Holy Name church recalls his term of service.
Father Tierney was an associate of Wendell Wilkie, who later ran for president of the US. When he died even the public schools were closed so the children could line the streets as the cortege passed.
I have no direct knowledge of the people you seek, but hope my info helps in some way.
