Looking for help with Peter John O'Reilly's family
My grandfather, Peter John O'Reilly was born to Michael O'Reily and Mary Anne (maiden name Cassidy) in Shercock, Cavan, Ireland on May 17, 1901. Michael owned a tavern according to a census I found and my father's explanation. My father indicates that Mary Anne died giving birth to their second child, likely a boy around 1903 and Michael remarried within a few years to a woman named Mary. My father also said that the tavern was taken along with a delivery truck used to make deliveries after a fight at the bar between two british soldiers resulted in the death of one of the soldiers. Peter John O'Reilly immigrated to the United States in 1928, arriving in New York and settling in Chicago where he married my grandmother, Nora Hughes.
I haven't been able to determine concrete birth or death dates for Michael O'Reilly or Mary Anne Cassidy that could help me find their parents or relatives.
What would be my best place to start? Any direction you can provide is appreciated.
