If not, you are in good company. Let me explain...
My family name (last name) is Greif, it is pronounced with a vowel like in Friday. It is German, and means griffin.
I first noted that the spelling of my name is causing difficulties for Americans, after my colleagues returned from a WWDC in the late '90es. When they mentioned their affiliation while talking to a Metrowerks compiler engineer, he responded something like
"we know a guy from the same shop, his name is Gabor Grief."They surely remembered my name because back then I bombarded them with many obscure C++ template compilation bug reports, actually causing them a considerable amount of grief. (They were really good in fixing them.)
Since then this is happening regularly. And I always explain patiently. Now, thanks to this blog, it will suffice to provide an URL :-)
As an aside, after spending my vacation at Fuerteventura in 2001, back on the airport I bought a bottle of Lanzarote wine with the name El Grifo. I have sworn to myself to only open it when I get a son. It took 6 years, and Helena came. The wine still tasted good, we enjoyed it with the family.
