Bain, Baine or Mooney

Hi.  I'm looking for any information available on my Grandmother and her family.  She was Lucy Elizabeth Bain and likely from Churchview, Tuam in Co. Galway.  She was born in about 1897 (Nov 22nd) and left for the States at about 17 years of age, settling in Chicago.  She had a large family in Ireland and most would similarly emigrate at a young age to the US.  As far as I know, her fathers name was Thomas Bain.  (I have also seen it spelled as Baine.) Her mother was Mary Mooney. Besides Lucy Elizabeth, they also had the following children: Joseph, Michael, Mary (Mollie), Frank, Susie and Katherine.  Katherine was the only child to remain in Ireland. Mollie would often take trips back to her homeland. In 1919 Lucy would marry James Dougherty and soon give him a son, named after his father.  She passed away in 1979. I have found some details on Mollie on ancestry sites but very little on any of the others and the trail has gone dead.  But I am hoping with the tidbits of information provided here, some kind soul could get our family research back on track.  Any help would be greatly appreciated.
