Aἰωνία ἡ μνήμη

In 1925, four young families- the Colokathis, Kyreages, Maglaras, and Polychronis families, living in Dover, NH decided to leave the Greek Orthodox Church.
Peter Colokathis, George Kyreages, Dionysios(Dan) Maglaras, and Arthur Polychronis frequented a Greek coffee-house in Dover. Here on serveral occasions they heard an itinerant preacher from Biddeford Maine speak about the bible. Frequently, discussions turned into lively question and answer sessions. It was a result of these sessions that these four young men began to gain an appreciation for the bible and for the love of God manifested in His divine plan of salvation. They purchased bibles and for the first time in their lives began to study them on their own.
As the years passed each family grew to include nine children. As the children grew older, there was some pressure on the parents by the children to join a "recognized" church because of the ridicule they were experiencing from their peers in school. In 1940, the Colokathis and Kyreages families made the decision to join the Advent Christian Church in Dover.

Lived in Dover New Hampshire, as a factory laborer, at Pacific Mills.
