I am a Civil War Re-Enactor with the 69th Pa Vol. Inf. and there is quite a bit of info on Col. O'Kane if you search the web with "Colonel Dennis O'Kane."Col. O'Kane is buried in Cathedral Cemetery at 49th and Lancaster Ave Phila. Pa. (Section U range 3 grave 27) This Re-enacting group arranged theplacement of the Grave Marker on the Col.'s grave some 8 years ago on the previously unmarked grave. Since that time we have had approx. 20 Markers placed on other Veterans of the 69th Pa Vol Inf. These the previously forgotten Irish of Philadelphia.
