Okay for Sz. Rycher I found Chaim Szmul Rycher born 20 March 1927 and he lived at Wald 26 flat 3. I also found him listed as Chaim Szmul RICHTER born 20 March 1927 and living at Sperling 14 flat 1 and Dunkle 19 and a date of 26/3/1943.
I found Leib Richter born 15 Feb 1889 (he also appears as Mejba RYCHER), Chana Perla RYCHER born 6 Nov 1906, Tauba RYCHER/Richter born 14 June 1932 all living at the same address. I found a page of testimony on Yadvashem for Hana Perel Richter b. 1906 and it says she died in 1943, and there is also one for Khaim Shmuel Richer born 1927. I'm assuming this is Chaim Szmul and his mother since the Submitter was Leib Richter, father and husband to the victims.
I also found that Leib was sent to Flossenburg on 28 Nov 1944 and given prisoner number 38514.
