Thanks for your reply. It looks as if Gitto is as far back as we can go! I have been looking at the name Gitto with a view to ascertaining if has an English equivalent... However, all I can find is that :- 1) Gitto is often an Italian surnameand 2) It is the name given in Welsh and Irish folklaw to a Griffin ( Griffiths , Gryphon etc). 3) It is also, very occaisonaly a Welsh first name, therefore is presumably Celtic in origin? So , perhaps , it's modern equivalent would be Griff - short for Griffith ?Ancestry.com seem to agree with this http://homepages.rootsweb.ancestry.com/~oel/givennames.htmlhttp://homepages.rootsweb.ancestry.com/~oel/givennames.html
( Although, some people consider Griff to be derived fromGriffin, being latin for Hooked Nose!)
4) Gitto could be a diminuative version of a longer name which ends ...gitto. 5) It could be a variation of the Cornish name Kitto, meaning son of Kit or Christopher.
