3,849 Global Ronan Family Members

I'm searching for the parents and birth county of my 3x great grandfather John Ronan born 1827. My ancestry DNA suggests Leinster, Ireland, but I know the Ronan name is popular in Cork. The following information I have documentation for: *Most likely immigrated to America during the Great Famine. I'm thinking between 1852 & 1855. Too many John Ronan's to find an accurate ship manifest. *Roman Catholic *Married 1857 in Huntingdon County, Pennsylvania to Bridget Bowen also born Ireland 1829. Witnesses to there marriage were Felix Toole & Julia Maher also from Ireland. *Four known children in order of birth: Alicia (1858), John C (1860)., Bridget Mary (1863), Margaret (1867) *Died suddenly 1894 in Huntingdon County, Pennsylvania from heart problems *Occupation: coal miner *Could read & write *Held various offices in local government *He was the enumerator for 1880 census for the township in which he lived. There was one other Ronan family living in a nearby county about 20 minutes from where John was living. I have not found the connection, but believe they may be relations. That family was Martin Ronayne b. 1822 County Mayo m. 1847 to Bridget Mullen b. 1829 County Mayo. They were in Pennsylvania by 1856. Their children were William, Anne, Michael, Mary, & Bridget. Any help will be greatly appreciated. I've been searching for 15 years to no avail. I'd like to be able to tell my father, who is now 70 years old, of his Irish ancestry.
