HI I found a posting on now-defunct Genforum for Egans in Philadelphia. My great grandfather Jack (John Joseph) Egan (Eagan) lived in Philadelphia for a while in the 1870s and worked on the trains as well before moving to Colorado in the 1880s. There were also Harrington cousins living in Philadelphia. (Jack's mother was a Harrington). I believe they came from Charlestown area of Mayo, but may have had cousins scattered around like many in Ireland did. I have found dna relatives who are Harringtons from PA.
