Sighinolfo I (Nolfo)da Montefeltro

I've been at this over 20 years, since the birth of myson.  The way I do this has changed considerably, not onlybecause of technology.  My interests have gone way beyond justmy son's ancestry, though that's quite a task [Scotland, England,France, Germany, Holland, Mauritius & South Africa].  Thedegree of rigour varies with how important it is to me.  Sothere will be errors, thousands no doubt.  Caveat lector.

Of course, additions and corrections most welcome
