Who is this couple? - circa 1960s - maybe BEBETSOS or friends of - Can you help?

Who is this couple?

This picture was among some that my paternal grandmother had when she came to live with us in 1963 after my grandfather's death.  We assume this couple may be part of her side of the family, BEBETSOS

My grandmother, Georgia Bebetsos, was born in Agios Ioannis Theologou, Municipality of Sellasias, Laconia, Greece and migrated to Chicago, Illinois, United States in 1916.  She left two brothers in Greece - Andoni and George Bebetsos.
