Thinking of you today and knowing how painful this was to my grandmother, who was your niece and great grandmother, who was your sister. It’s strange how I live in the same area where this occurred. East Lindsey Ave. Cedar Grove. Christmas that year, 105 years ago, was changed forever for them. - S. LiCalsi, Verona, NJ
