Born in Tunis, French Tunisia, around mid-1950 while her parents John Lazare and Ines (Agnes) were running a regional US-affiliated field hospital in Sousse, North Africa. Baptized Eftichia after her paternal grandmother Eftyhia Karamitrou — the Greek tradition of naming the eldest granddaughter after her father’s mother. She traveled with her mother on the SS Constitution from Cannes to New York on November 30, 1951, where she appears on the manifest as “Eftichia C. Jeannopoulos,” age 1½ — the “C.” being her American everyday name Claudine.
The May 2026 conversations with her sister Aline confirmed that Eftichia and Claudine are the same person: the Greek baptismal name on her early documents and the American name she went by in adult life. She married Patrick Boyhan.
She is one of John and Ines’s three daughters, alongside her sister Mya Durso (adopted, d. 2002) and Aline Pepe.
