Hello,
Jewish children at birth were identified by their given name and father's name only.
for instance, if a boy was named Moshe, he would be recorded as Moshe, son of David.
The surname was frequently omitted from the records.
It is the same with death records, it is common to omit the surname from Jewish headstones.
Do you have a location of birth and given name of the son and father?
cheers
