Researching Marion Clancy Born 1906 Ireland

My grandmother, Marion Clancy, married Walter Wood from Herkimer County, NY. She has told the family that she came over on a boat with her mother from Ireland when she was a baby.She didn't remember her father. However, her mother died when she was around 10.
I have found her on Ellis Island records arriving from Killaloe, Ireland with her mother, Mrs. Clancy. They were on their way to see husband Michael Clancy from NY. Any insight would be appreciated.
