KASHWER - does anyone know of this name?

I'm looking for anyone who knows the family name - KASHWER in Lebanon. I've been told that it is Shiite and most likely is in the south, but I can't find anyone who actually knows of the family. I have an old family photo (1930's?) with 6 people. The name KASHWER is on the arabic inscription. I can email the photo and inscription.

Any suggestions appreciated !!
