The list of Jewish Families of Dvinsk shows Musa Hurwitz as the Wife of Elia. She was 48 in 1882, born about 1834 and was from Daugavpils.
There is a second entry for a wife of Elia and she is Sora Musa age 37 in 1876 from Daugavpils. She is shown as age 37 in 1876 indicating a birth year of 1839.
For now I think these two women are the same. I have noticed that people seem to be born later as they get older. If we had the fathers' names it would be easier.
There is a distinction in the record between Elia and Elia Peretz. Furthermore, Elia already has two wives.
