Angela,

I believe this is your family; everything matches.

According to a New York Passenger List on Ancestry.com

This family is returning to New York from Naples, Italy, August 30, 1951 to September 7, 1951.

GROVES, Morton, 50, birthplace is Indiana
GROVES, Sarah, 48, birthplace is Mississippi
GROVES, Beverley, 19, birthplace is Pennsylvania
GROVES, Victor, 15, birthplace is Pennsylvania

Morton Groves has his surgeon's ID code on this form.

I also found this family on a passengers list for a cruise to Nassau, Bahamas.

Victor Morton Groves also became a surgeon. He graduated from Kings College in Wilkes-Barre, Pennsylvania and Howard University College of Medicine in DC.

Victor M. Groves passed away on January 7, 2000. He lived in Harrisburg, PA.
