Indeed, like me, most Dutch people are known as "Mr/Mrs Van" in foreign correspondence.
Presumably some "Mr/Ms de" too.
And these days, more than a few Ibn, Bin and Al folks too, I should think.
Where I hail from, the last name is often the name of the farmstead. And they often have qualified names like "North Hill", "Lower Pond" or "Large Valley Farm".
Add that it's not uncommon to combine the names of your mother and father, or for women, keep your old name and tack the new last name to the end.
And finally, interject patronymics.
So you can end up with full names like "Daisy Franksdaughter North Hill Lower Pond Large Valley Farm", and that's with no middle names.
The "short forms" could be either of "Daisy Franksdaughter" or "Daisy Large Valley Farm" depending on context.
Someone else might be named "John John Johnson Johnson Johnson".
Truly, the only sane solution is to let people enter their own names and desired forms of address free-form.
