TWO OLD CAUCASIAN TWIN SISTERS ON BATTERY PATH [????- ]

Two old Caucasian twin sisters on Battery Path

I used to live on Robinson Road until 2012. Every morning I took the bus to the Central, got off at St. John's Cathedral and walked through Battery Path to my office. I used to see two old Caucasian twin sisters there either walking or sitting on the bench reading. They carried quite a bit of belongings in plastic bags with them. They were very quiet and, most of the time, I saw only one but not both together. I am not sure if they were homeless. Does anyone know of them and whether they are still around?
