Bahz-il only in front of the last name Rathbone.
Bay-sil is the herb. And a very useful one, at that!
Speaking of which:
Herb pronounced without the H = 'erb, is what grows in your garden and you add to food.
Herb pronounced = Her-b is a man's name.
I don't speak English. I speak American. With a sort of a freakish Texas twist on it. There were two Tommy Lee Jones movies on in the last week (Volcano, which is a hoot, and Men In Black) and the damned Texas accent came slamming back. Went to a shop the day after MIB and was browsing the jeans section when they started playing Hank Williams, Senior, on their music system.
I didn't dare open my mouth the entire walk home, because when I did I sounded like "home folks." (AKA, Tommy Lee Jones is from my old stomping grounds.)
I think it's gone again now, thankfully!
