Aaron Moses Wander #names


I am trying to find the mother, father and spouse of my great, great grandfather, Aaron Moses Wander from Brest Litovsk. Any other advice on the Wander family would also be very welcome. Aaron's son, Benjamin, migrated to London around 1890 and married Esther Levinson in 1892 at the East London Synagogue. Around the same time the family name was changed to Wonder.  Any assistance would be much appreciated.
