but names can be a little different. For instance, I have an unusual last name that others with the same name (not relatives) pronounce differently than my family does. They are spelled the same but it's another case of vowels being said differently.

I know several people who have the family name of Epstein, all Jewish. All of them say Ep steen.

Asking Google how it is pronounced suggested this is the most common pronunciation on North America. They mention this could be rooted in Yiddish.

They mention your pronunciation and say it is closer to the German pronunciation.

I have not heard a single person who knew Epstein pronounce the name as anything other than Ep steen.

I'm only reading the name whenever it's printed in the news or on the internet, even here on DU.

I can't help it, I read this name as "Epstine" because that's how I am trained to read German.
If I were a TV newsreader I would have a real problem!

To me -STEEN is like fingernails on a blackboard.

I can't go against my training in German pronunciation.

Furthermore, I've spent seventy years hearing people mispronounce my German surname.

Now, if we're going for the Yiddish pronunciation, wouldn't it something like "Epshtayn" ?

Here's an American example, (because I live in Pittsburgh, PA) many people around here say the word "creek" as "crick." We all know what that word means when we hear it, but it's not "hoch-Deutsch."

Also I read your name correctly, with no problem.
