Ludwig lived in Aachen. In the 1887 address book he is listed at Augustastrasse 20; in the 1899 address book he is listed at Roonstrasse 1.



I am indebted to BS who has found the graves of Ludwig and Clara Jarislowsky in Aachen's Jewish cemetery and has provided their dates of birth and death. In the absence of documentary evidence I assume that Clara was Ludwig's wife, and mother of Hans and Hermann.
