Having roots in 3 different cultures has been and continues to be a very emotional and moving experience.
    
My brother and I are trying to put together a Buffalo-Coker Family Tree. Towards that end he found a 1920 & 1930 Census on Ancestry.com. I've put what he found in a PDF file.

My Black Heritage
    Both of my grandmothers were Black and daughters of freed slaves. Neither of my grandfathers was Black. That makes me half Black. For the record I am one fourth Native American (paternal grandfather) and one fourth Japanese (maternal grandfather)
My Japanese Heritage
    
My maternal grandfather was Japanese which makes me one fourth Japanese. What little I know about him is anecdotal.
    
He was either an orphan who got adopted or was just adopted. Sato was the family name of his adoptive parents. He apparently was a fisherman. On a trip to the United States he jumped ship and asked for and received political assylum. While here he also worked as chef. He was a great chocolatierre and used to make and sell them around the neighborhood.
My Native American Heritage
    
My paternal grandfather was Native American. As far as I can tell he was born in North Carolina and was of the Blackfoot tribe.
    
I am planning on a trip to North Carolina as soon as possible to research this side of my family.
