I have actually been wondering how your friends pronounce "Ry" Is it more like "Ree" or "Rye"
It's exclusively used in writing. I started using this as an abbreviation of 'Ronny' (that's how my friends address me). I'm always very suspicious when people call me Ronald... they're probably tax collectors or other 'officials' I'd rather not meet

Now for the correct pronunciation of my name:
The 'i' in 'Kint' is pronounced as in 'hint'.
Well, 'Bruyn' is probably the most difficicult part because that uses a diphthong which is unknown (?) in English. Even in modern Dutch the "uy" combination has become obsolete. The 'y' was only an indication of a prolongation of the preceding sound, in this case the 'u' as in 'hunter'. Originaly that was pronounced as 'uu' a bit as in 'Van Buren', but still a bit prolonged. Later it became the diphthong 'ui', pronounced (approxiamately) as 'u' (hunter) followed by 'i' (hint). If you learn to pronounce both these sounds in a quick succession, then you come very close.
Note that this is the same sound as in Nicholas de Bruijn's name as 'y' or 'ij' were used for the same purpose.
Finally the 'seels' part. Here the 'ee' sounds not at all as in 'seals' or 'wheels', but rather like 'sails'.
