Excellent question. My name is Thijs Roes, pronounced "Tice Roose".
The name 'Thijs' is easy to pronounce if you grew up in the Netherlands, as I have. Here, the Dutch invented the concept of the letter 'ij', which is a so-called digraph prounounced as the I in "rice", "spice" and "mice".
It has been a good source of Scrabble family fights throughout Dutch history. Is IJ made up of an I and a J, or is it actually the letter Y? It is a tedious issue in the Netherlands and I wouldn't be surprised if it has broken up some marriages before Google could give a conclusive answer. (They are two seperate letters, but pronounced as one.)
Besides arguing about Dutch orthography, I also spend my days as a creative journalist. I do full communication productions. I report, film, write, shoot, edit, advise, tape, produce, publish and run a business.
