While it can be confirmed that Joan’s middle name is Alice not Celia, dealing with Jocz family names is not so simple. Jakób’s mother’s name is variously recorded as Hannah, Chana or Anna. His father could be Bazyli or Basilius. This is explained by rendering names in different languages as well as by efforts during WW2 to mask origins. In general, documentation created for this site uses the names by which living family members knew them. Other contributors made different decisions.
