Was Wanda Berbecka a daughter of General Leon Berbecki?

We are seeking documents concerning Wanda Berbecka. A reference in personnel records reportedly identifies her as the daughter of Lieutenant General Leon Piotr Berbecki and Zofia née Jacyna-Jatelnicka, born on 24 September 1907, probably in Kharkiv.
A further public clue appears in the index to Jan J. Jadacki’s memoir “Na Mazowszu i nie tylko”: “Wanda Berbecka – Leon’s daughter, a school friend of Anna Jadacka from Grodno.” We have not yet found Wanda’s birth record or reliable information about her later life.
We are particularly looking for a birth or baptism record, residence and school registers, a marriage or death record, photographs, letters, or family recollections. Did Wanda live with her parents at 50 Starososnowiecka Street in Sosnowiec? Did she later live in Grodno, Warsaw, or Gliwice? Did she marry and use another surname?
Confirmed context: Leon and Zofia married in 1906; Zofia taught in Kharkiv and Sosnowiec and later served in the Polish parliament. Public studies most often give Leon’s dates as 28 July 1874 – 23 March 1963, although records and older publications differ. Please provide photographs of documents together with the archive, collection, and reference number.
