Thank you!. I was torn about whether I had enough info to go with the Helen on Main Street--but to hear you feel confident, makes me certain now. You also helped confirm who Ellen's parents were and that they (as I suspected) were born in Ireland.
I had not looked at Bridget McCarron McInilley, so that is the next place to go--thanks!
And, yes, Thomas' son Leo drowned at 16 or 17 years of age and Thomas died two weeks later, tho its not clear that he was ill. I've been able to find some newspaper articles that fill in some missing pieces. Sad story.
