Looking for Information on Thomas Quinn Born Approximately 1854 Father of My Paternal Grandfather John a Quinn Born 1877 IN Pennsylvania

Thomas was married to Catherine Gorman and I believe they had 3 children, John, Bernard and Francis. The family was Irish but I'm not sure when they came to the US or where they were from in Ireland. John worked as a clerk for the Pennsylvania Railroad and married a Rosanna Golden in 1905.
