My Mom knew a cute little boy over in Sweden when she was a little girl. and his name was Roland. Damn, and she had to hang that name on me when I was born. Now I would have to wear a tie, if folks called me by that name, so as long ago as I can remember, I have been called Roly. Not pronounced Rolly, (like in Holly, but Roly, like in Holy)
In all of my travels and of any of the guys that I have met in the construction trades, I have never met another Roly. Actually, it is kind of nice, calling a busy building inspector in downtown Los Angeles and telling him "Hi, this is Roly........and he know exactly who hs is talking to. Folks mispronounce it often, making it sound like Raw-Lee, not Row-Lee.
To help them remember how it is supposed to be pronounced, (if I am going to have more than a short friendship with them), I tell them the following: Imagine being in a row boat with Robert E Lee, and we are about to be swept over Niagra Falls, and he is the only one with oars. At this time they would be shouting my name, as loudly as they could.......ROW LEE! This always gets a snicker and also gets the name remembered correctly.

Roly, not Rolly, Rollie, Rawleigh, Ronald, Ronnie, Ron or Roll, Just Roly, with a long "O"
