Rita Weinraub is the biological mother of Abraham Morgan. Abe found out his real last name and who his parents are in the episode "Hitler on the Half-Shell."


Abraham was found at a Nazi concentration camp so it is assumed that Rita and her husband Hermann Weinraub were Jewish. They had Abe most likely at the camp or right before they were sent there. It is assumed that both Rita and Hermann were killed there or just lost and never reconnected with their son. When Henry Morgan found Abe as a baby, he adopted him so Abe never actually knew his biological parents.
