Two George Stratigos' in Kythera

Please help me find the family connection between these two George Stratigos' from Kythera.

My wife's ggrandfather is George SPYRIDON Stratigos, born in 1850, the son of Spyridon George and Kyriakoula in Milopotamis.

The other George is George NICHOLAS Stratigos, born in 1859, son of Nicholas Theodore Stratigos and Lygere Poteris.

Can anyone help me find how these two Georges are related, if at all?

Thanks!
