There was only one person who matched for M. Szwajcer born between the years 1921 and 1927. He was MOJZESZ PINKUS SZWAJCER born 4 April 1923 and he lived at Gerberstrasse 13 and Sperling 15 flat 6 and he changed addresses 3/1/42 to Hanseaten 4. He appears as a second time with the addresses Hanseaten 41 flat 2 and changed addresses on 19/8/42 to Hanseaten. He appears for a third time with the address Hanseaten 61 flat 24 and Hanseaten 41. He has a ghetto note that says, "ABG SEPT 1942 A.G." I'm not sure if this refers to him changing addresses in September of 1942 or if he was deported to Chelmno in September of 1942.
ABG + date: Change of registration to new address
AG or A.G. + date: Change of registration to new address, or deportation (to Chełmno); AG may be used as an abbreviation of either "Abgang"or "Ausgang"
