I'm also researching Fallons. Mine are from Mayo. If you ultimately get back there, please keep me in mind. I traced the family forward.
If this is the right family, here is the mother and two sisters in 1920 while Patrick was in Joliet. https://familysearch.org/pal:/MM9.1.1/MJW9-8RX
This is the info for Joseph while in Joliet:https://familysearch.org/pal:/MM9.1.1/MJ8M-FTS
These are likely the siblings in 1930 and 1940. https://familysearch.org/pal:/MM9.1.1/XSGN-GQQhttps://familysearch.org/pal:/MM9.1.1/KW1B-J1K
I never found Edward after 1910. Unfortunately Joseph Fallon's sister Elizabeth Fallon Cogley's children are all diseased, but maybe you could post some of this additional information on forums to find her grandchildren. Perhaps they have handed down some family information.
