Dina's father Rabbi Eliezer Liepman Philip Prins (1835-1915) was a Torah scholar who published many novellae (chidushim). He used to give shiurim in his home on Sabbath afternoons. He spotted among his pupils a young man who impressed him - Jacob Eisenmann - and to him he gave his only daughter, Dina, in marriage.

After Jacob Eisenmann's death in 1913, with the outbreak of WWI, the Belgians evacuated all German subjects from their territory, among them Dina Eisenmann and six of her eight children (two were already married). As her oldest daughter was married to Rabbi Joseph Breuer and lived in Frankfurt, Dina Eisenmann settled there too.
