A tough one for sure. Pretty much your call after all the input.

My life changed radically when the clown on the flying hamburger was invented by the golden arches people. Often thought of changing my name to avoid the teasing and repeat stupid jokes.

But, bottom line, my blood is Macdonald so I keep the name. Guess using that logic you should revert to your ancestral spelling. But, I'm not sure I would were I in your situation. A personal call.

The Welsh comments reminded me of a joke I first heard as a Hopi joke, but it would fit equally well for the Welsh...hope its within bounds...

What does a Welshman have that is long and hard that he gives to his bride on their wedding day?

His last name....
