Found my map. It's a "tourist map" and doesn't cover the entire city. It does show "Summerhill" as an extension of Parnell Street and just south of Mountjoy Square. Unfortunately, Mountjoy Square is at the very top of my map. It does show a road perpendicular to the square on the east that is without a name on my map. It runs north from Summerhill. Perhaps that is Fitzgibbon St. Doesn't indicate which one is higher or lower in elevation. No topography shown. Thanks for the tip, Deskjet.
