It looks like my solution can easily handle that
```
^(?=([A-ZÀ-ÝŐŰẞŒ]|([a-zß-ÿőűœ][ '])))(?=(?![a-zß-ÿőűœ]+[A-ZÀ-ÝŐŰẞŒ]))(?=(?!.*[A-ZÀ-ÝŐŰẞŒ][A-ZÀ-ÝŐŰẞŒ]))(?=(?!.*[- '][- ']))[A-ZÀ-ÝŐŰẞŒß-ÿőűœa-z- ']{2,}([a-zß-ÿőűœ]|(, Jr.))$
```
<!-- begin snippet: js hide: false console: true babel: false babelPresetReact: false babelPresetTS: false -->

function myFunction() {
const pattern = "^(?=([A-ZÀ-ÝŐŰẞŒ]|([a-zß-ÿőűœ][ '])))(?=(?![a-zß-ÿőűœ]+[A-ZÀ-ÝŐŰẞŒ]))(?=(?!.*[A-ZÀ-ÝŐŰẞŒ][A-ZÀ-ÝŐŰẞŒ]))(?=(?!.*[- '][- ']))[A-ZÀ-ÝŐŰẞŒß-ÿőűœa-z- ']{2,}([a-zß-ÿőűœ]|(, Jr.))$";
var regex = new RegExp(pattern, 'gm');
var a = document.getElementById("myText");
var b = a.value;
var c = regex.test(b);
var d = document.getElementById("result") ;
d.innerHTML = "Result:";
if(b != ""){
if(c){
d.innerHTML += " passed";
}
else{
d.innerHTML += " failed";
}
}
else{
return
}

<h2>Name Validation Regex Pattern </h2>

Try this one
```
^[^- '.](?=(?![A-Z]?[A-Z]))(?=(?![a-z]+[A-Z]))(?=(?!.*[A-Z][A-Z]))(?=(?!.*[- '][- '.]))(?=(?!.*[.][-'.]))[A-Za-z- '.]{1,}$
```
There is also an interactive [Demo][1] of this pattern available at an external website.

Edited:
New one supporting most of European languages:
