If you’re naming a child, YOU decide how you want his name pronounced. There is no “correct” way to pronounce a name. It’s unique to every person.
Our daughter’s name is Evangeline. (simliar to Augustine, right?)
How do you pronounce it? Many people say, “Ee-van-juh-lyne,” accent on the second syllable.
A few say, “Ee-van-juh-leena.” (Germans?)
WE say, “Ee-van-juh-lin,” accent on second syllable. And that’s how she says it, and that’s how people who are introduced to her pronounce it.
The other pronunciations are just fine, but we chose to say “Ee-van-juh-lin.”
We actually have more trouble with our second daughter, whose name is “Charity.” Nice and simple, right? WRONG! So many people call her “Chastity,” or “Chassidy”. How do they read those out of “Charity?!” Oh, well.
