Robert is my dad, also known as Bob (that’s what Mom calls him. He is quietly religious, and an understated intellectual. I get my introvertedness and love of reading from him, no doubt.
Robert (Jr.) is my brother. He is developmentally disabled, has a sweet tooth (we all do!) and loves all sorts of music, but especially that B96 techno/house/dance mix stuff.
Only one Bob around. He lives in a drawer in the nightstand… 
I have a wonderful cousin named Robert.
We have a wonderful cat named Bob.
I had a fantastic science teacher in high school named Bob.
We had an idiot in that same science class named Robert, that science teacher Bob yelled at a lot.
That about covers it.
Robert Lee (my grandfather, and the man I’m named after)
Robert Lee, Jr. (my father and the world’s best father)
Robbie (my great nephew, who, while only 3, is “meaner than cat shit” as my Grandmother would say)
My accountant is Bob. I have a coworker who’s also named Bob. And there was once an Attorney General named Bobby who I liked a lot.
