My father had a friend named Horace, with a middle name that was even worse, III. That right, he was the 3rd generation with that horrible name. He got a lot of pressure to name one of his sons Horace IV. He had a spine and his sons have much more normal names.

Oops. I just did the math. Horace III was born in about 1925. So Horace Jr. was born about 1900, and Horace Senior was born about 1875. Back then Horace was a very normal, reasonable name.
Horace III's sons were born in about 1950. Refusing to name one of them Horace IV makes perfect sense even if his older relatives didn't agree.
