Harris Family Genealogical Record According to the 1900 Census

Now, we think that this Harris family were the parents of my great grandmother. The names are all confused. My great grandmother told my grandfather that his grandfather's name was Johnny Harris? and that his grandmother was Lucy Harris.

The 1900 Census shows the following record:

William Harris and Lucy Harris are the parents of Rosa, Gene, William Harris Jr., and Luella Harris. They are living in Clay, Mississippi, Bt 2

The ages
Rosa age 7

Gene age 4

William Harris jr. age 2

Luella age 11

My grandfather also had an uncle named Johnny Harris. I have searched and searched and find no record of a Johnny Harris in this family. I wonder if the brother Gene's name was somehow incorrectly pronounced Johnny......hmmmm
