I think they are two different persons, by chance with the same name, and with a dance teacher father.
1. the ages are different - 1st is 88 in 1901, 2nd is 84 in 1890
2. mother of 1st is Henriette Lichtnenstedter, of 2nd Friedericke Lichtnestad
3. father of 1st is Levi, of 2nd Israel Levi
I am sure they are family, but different persons. Is there a place mentioned in the certificates?
