Famous British composer-conductor Avril Coleridge-Taylor (1903-98), daughter of white mother and of the acclaimed highly gifted London-born violinist and composer-conductor Samuel Coleridge-Taylor (1875-1912), whose father, descended from slaves in America, was from Sierra Leone. Samuel died tragically young. Avril used her middle name in preference to her first, Gwendolen. She was prevented from performing in South Africa when the apartheid regime, which had permitted her entry, discovered her mixed parentage. She wrote some of her works under the alias Peter Riley. A remarkable woman. So much for the name Avril being "trashy" as some commenters allege!
In the 1960s there was a South African man called Avril Malan. He pronounced it AH-vRil, and since he was the Springbok rugby captain and a very tough guy indeed, he clearly had no problems as a result of his name. There have been other male Avrils, but he's the most prominent by far.
Hi, I got this in a dictionary: "In Unreal Tournament 2004, AVRiL is an acronym for Anti-Vehicle Rocket Launcher. The small "i" is added for easier pronunciation."
