barrysloateI think Hal's is the best, but I believe you would have to say "I have two Ross Youngs." The alternative is "two Ross Youngses" and I can't imagine that's correct as you can barely pronounce it. It might be an exception to the common rule of pluralizing.
Here's one: if you were referring to the wife of your boss, you would say "my boss's wife". While there is an apostrophe, it's the only example in the English language I can think of where you would have a triple letter repetition.
Edited to add proper names are often tricky.
