We may have found his father the same way we found his mother. We were searching for more possible relatives and we may have found his father, as well as an older brother and an older sister. Dawid Ajzman would have been in his late thirties when Mojsze/Mordechay was born, and lived at the same address. Also, Eta Ajzman, born in 1926, and Lajb Ajzman, born in 1921, both lived atthe same address as well, though they could have been cousins or had another family relation as well.
From what we have recently learned about the Chelmno facility, we think we can assume that Ajzman died there. He was sent there March 15 1942 and in March 1943 the camp was decommisioned. Any remaining prisoners they had they blew up with the castle they used for their facility. Also, according to the website, Only four prisoners from Chelmno escaped, and none of them have a name that is remotely close to Mojzse or Mordechay Ajzman.
