JRI-Poland cites a record from Sohrau of the marriage in February 1872 of Eva Berger aged 29, daughter of Solomon Berger and Ernestine geb. Krakauer. A note derived from ancestry.com says that Ernestine geb. Krakauer was the second wife of Salomon whose first wife was Rebecca Spitzer. Given her age at her marriage, Eva must have been born February 1842 to February 1843. This date of birth puts Eva within the scope of the Pless records which list the children of Salomon and Friedrike geb. Spitzer; these records include children born from 1834 to 1844 as well as a move to Sohrau in 1845, yet they do not mention Eva or Ernestine. With Simon being born in April 1842 Eva was probably his twin (or else conceived immediately after his birth and born premature), so her omission is all the more extraordinary. While Ernestine's absence from the Pless record could be explained by her not marrying Salomon untill after the move to Sohrau (and so being Eva's step-mother rather than her biological mother), Eva's absence from the Pelss record leads me to suspect that the husbands of Friederike and Ernestine were not the same person.
