It was a great day for thousands of Emerald Isle ancestors, from the Civil War re-enactors of the 69th Pennsylvania Irish Volunteers, to Philly cop Kim Miller and her daughter Maggie, 13, who prayed for the safety of all police, to Miriam Sands, 84, bundled against the cold at Fifth and Market, waiting with three generations of family to see her sister Natalie Smith, 81, march with Port Richmond’s Ladies Ancient Order of Hibernians, Division 87.
