SAPHIR and LEINER Surnames

Hi All,
Im helping a family to try and find out what happened to the family in the war time.
One of the sisters came to Israel in 1935 and her parents and 2 sisters were gone.
We have found the borth register of 3 of the sisters - one died at the age of 3 so she did not suffer the war.
I see the surnames SAPHIR and LEINER mentioned in the main project page (attached link) - in list of surnames
Im asking what is the source to include these names?
