Before Sarah, Abraham was married to Elle, but she died in 1848. He had at least 2 children with her, meaning that Bertha had half-siblings.
Bertha’s half-siblings, Abraham’s and Elle’s children, were both born in Brody and raised by their stepmother, Sarah:
- Eidel Neche, a daughter, born in 1847
- Ephriam Beer (Bernhardt), a son, born in 1844 in Brody and died in 1909 in Vienna
Not much is known about Eidel Neche but Ephraim (Bernhardt) had at least 9 children who would have been half-nieces and half-nephews to Bertha. Some of them had very interesting stories which you can read about on Ephraim’s page.
