According to family lore, Blazo is a french name, the first Blazo originally came from Bordeaux, France, he was supposedly a priest who left France, left the church got married and had a family and settled in Greenland, NH. Census info lists many names similar to Blazo, I believe they are all descendants as the Blazos seemed to dissapear. Other names are: Blaze and Blaxo. Hope this is helpful.
