My father was Robert Charles.
His son (my brother), is Robert Allen.
My brother’s son (my nephew) is Robert Matthew.
Same first name to carry on the tradition, but different middle names to avoid the Sr., Jr. III, IV, V, etc.
Same thing on my mother’s side, with my uncle, cousin (his som), and cousin’s son all named Daniel with different middle names.
I was supposed to be named after my grandfather, but my mom wanted a “beautiful” sounding name, so she named me “Alonzo”. I hated it. So when I grew up, I just went by my grandfather’s name, which is also my middle name; Lee.
