An ecclesiastical certificate of Constantine’s birth and baptism, issued by Metropolitan Iakovos of Mytilene on August 24, 1937, Protocol No. 1575. The letterhead reads “ΒΑΣΙΛΕΙΟΝ ΤΗΣ ΕΛΛΑΔΟΣ / ΙΕΡΑ ΜΗΤΡΟΠΟΛΙΣ ΜΥΤΙΛΗΝΗΣ” — “Kingdom of Greece / Holy Metropolis of Mytilene.”
The certificate states that on June 19, 1916, was born to the lawful spouses Lazaros Yannopoulos and Eftychia Karamitrou a male child who was baptized by the priest Oikonomos Papatheodorou, then parish priest of the Church of Saint Therapont, with godparent Emmanouil X. Georgiou naming him Konstantinos.
The document is a re-issuance, based on a fresh August 21, 1937 affirmation from the parish priest — produced because Constantine, then a medical student in Rome, needed Greek-state documents and (as the contemporaneous Mytilene law-office letter explains) “there was no civil-registry act.” Greek state authorities therefore had to derive every Constantine document from the original 1923 parish baptismal record.
This is the document that introduced June 19 as Constantine’s birth date into the Greek state record. The 1923 priest’s original certificate had recorded June 15; the 1957 Mytilene Δημαρχείον re-issuance later inherited the June 19 date from this Metropolitan re-issue. In US records — including his 1941 WWII draft card and his 1947 Certificate of Citizenship — Constantine consistently used June 21, the family-memory variant. Three dates, all referring to the same boy, all traceable to the absence of a civil registration of his Asia Minor refugee birth.
