Michael W O'Brien

Hello! I am looking for information on my great grandfather Michael W. O'Brien's parents, John O'Brien who was born abt 1838 in Coraigh, Co. Cork, Ireland. He emigrated to the US most likely before his 20th birthday. He settled in Hopewell, Ontario Co., NY. He married Julia Delia O'Shaugnessy. Apparently, he ran a bar in Canandaigua, NY. until the children "became of age". He also lived in Rochester, NY. In later years he lived with his son Michael W. at the Cobblestone Farm on West Lake Rd, Canandaigua, NY. John passed away on May 8 1930 in Canandaigua at the age of 92. Michael W. passed away in Canandaigua on April 20,1937. Michael was married to Mary Elizabeth "Libbie" Foley. My grandfather was Stewart, Michael and Libbie's son. I would appreciate any information you may have. Thank you!
