Great Question, as far as I have been able to un cover it does not have a meaning the way
Butcher,
Butler,
Peterson etc does, but it is also known to be a first name without the s at the end, theres at least one
Greek movie using the name as a title and at least one cargo ship out there with that name. It is very popular in Chios, most of them are related, I do have a few more tidbits to exchange with anyone willing to add to what I've posted. Thanx PG
