Ruta Moszkowicz has a sister Mala, who is a doctor and is older than her by a few years.
I understand that Ruta never married and has had some psychiatric problems.
She should be now about 63.
She was a very talented girl who recited poetry in Park Kasprowicza.
She lived in the same block as us, in Szczecin, on the top floor, ul Heleny 17 numer 9 czy 10.
She was very beautiful, with thick platted hair.
I think nowadays she lives in Sweden or Denmark.
Hope this helps.
