Thanks for the information on Breens. Charles may be a good clue for the next hunt. I'll pass this info along to the friend I was helping and see if she can connect and share anything back. I'm appreciative of what you have shared and anything else that may come to mind re the Breens.
I did search through cemeteries in Wenona and Streator but didn't find the names given me. Now to check out Charles's records. Do you know where in Iowa he died?
