BLinda...
You aren't gonna believe this --I had to be convinced myself. My sister-in-law's niece (her husband's niece, therefore no relation to me except that murky "by marriage" thing) had a baby this weekend. Guess what she named him?
Alexander Evan!
And my sister-in-law swears her niece had no idea my boys were Alex and Evan.
My Evan is Evan Harrison. My Alex is Alexander Joseph. We thought Joseph Alexander flowed better, too (similar to your thoughts), but we really wanted to call him Alex. I go by my middle name and have spent my entire life explaining that to people, so I wanted "Alex" to be his first name.
We spend so much time working this stuff out, don't we, and then they come up with their own nicknames! Currently Alex likes for his friends to call him Al, which I think sounds like a used car salesman you'd see on one of those cheesy ads on cable TV at 2:00 a.m. Meanwhile, Evan's friends are calling him Cheeto, which he solemnly advises us is his new "Spanish class" name...
P.S. -- we don't have a drop of Greek blood either -- or, for that matter, Welsh blood (Evan is the Welsh version of Sean, which is the Irish version of John.) My kids are nearly 50% Irish (from me on all sides of my family; I had one English great-grandparent and everyone else for three generations back is Irish) and from my husband's side they've got Russian, Polish, Hungarian, German and maybe a little else of this and that thrown in, too. In our household we say the dog's the only real purebred!
Enjoy your boys! Isn't Cathe in for a treat!?!?
