Seek more information of Andronicus and Stathis

Can anyone give me any more information about Elly Andronicus? Or John Stathis? In early 1850's onwards, because they had a son born in 1897.

Elly Andronicus had married to John Stathis.

They had a son named Nicholas Stathis.

He was born in Hora, the Capital of the island Kythra in Greece in 1897.
