The surname Galette, where did it come from?

I have no idea where your source is for current statistics, that many AA have this name. I can tell you where to find historical records...www.familysearch.org will have census records from prior to 1930. Freed former slaves took names after emancipation, by their choice. Sometimes the name was their prior "owner", but not always. You are also ASSUMING that any caucasian with the name has roots in Italy, which is nothing more than a guess. It is completely possible that they have a name which evolved from something else..ie Gillette. This is very common. I find only 18 persons in the social security death index with the name..and remember that the females there would generally have the name through marriage. The bottom line is that EACH PERSON with the name is an individual, who may/may not have Italian ancestry, or may/may not be African American. You have to learn the specific ancestry for any person, to determine their origins (and not by surname).

Galette immigrants in the 1920 census were born in Italy, Greece, Canada and Puerto Rico. All were listed as white except one mulatto couple. There are a few in the passenger lists from Sweden, France, Italy.
