Looking for my Lazzareti family

Hi everyone,
I am trying to track down my Lazzareti (also Lazarette/Lazaretti) family.
My Great grandfather (Alexander) was born in Crete (circa 1854) and his brother Dimitre (Demetrius) was born in Cerigo (circa 1856).
Their parents were Constantine (a solicitor) and Drusa (nee Carusa).

Any information on any of these names would be very much appreciated.

Likewise, if anyone knows of any living family members with the name Lazzareti (or close variation) in either Kythera or Crete, I would love to be able to contact them.

Regards
John Kingston
