Hi Margarita,
I suppose that Yad Vashem has scanned copies of the questionnaires submitted by Jeno and Armin Leicht which may be released and viewed onsite. But...Traditionally, a. Hungarian married woman used her husband's complete name adding the suffix "ne" (Mrs.). In your case, the registered names should be Leicht Jenone and Leicht Armine, respectively. If indeed the questionnaires were filled out as I suppose, there is not a direct way to find out their names. I did find out that Jeno registered his spouse's birth date.She was alive in 1945 and living with him.
