I am Nicholas Rossolimo's grandson. The last name is not Italian at all. It is indeed Greek in Origin (probably "Rossolimos," the "s" dropped a long time back). Rossolimo was my grandfather's original name in Kiev (remember Ukraine was part of the USSR at the time). The Russian name some people here heard -- "Verukov" -- is close to his mother's maiden name; perhaps he used that while playing in the USSR; afterall, a Russian sounding name would go over better in a Communist country where they did not like Western sounding names (Rossolimo sounds Italian).
