Aside from shared descent from 5000 years ago, there is some shared descent from Aegean migrations into the Levant and later MENA migrations into Crete. Also, I recall you being from Crete. I also wouldn't be shocked if all Cretans had some Jewish descent today:
https://www.jewishvirtuallibrary.org/creteQuote:
Under the Byzantine emperor Theodosius II (408–50) the Jews of Crete, among others, were severely oppressed. Possibly in consequence of this in 440 they placed their faith in a pseudo-messiah, who claimed to be Moses sent from heaven to lead the Jews of Crete dry shod through the sea back to the Promised Land. Of those who did not drown after jumping from the cliff, most converted to Christianity.
