This is a long shot, but during WW2 my mother worked with a Polish woman she called Evelyn and this is phonetic, Las-chover with the accent on the final syllable.
I have been toying with some time and think she may well have anglisiced her first name from Ewelina and that her last name may be either Laszczowa or Łaszczowa, but I don't know whether either of those would work as a surname.
Either way, I think she probably went to the US after the war, but I cannot find any trace of her.
Thanks
