As for siblings...
I'm the oldest of four boys, and we all basically were born one right after the other - good Catholic family.
My brother, Don, was born a month premature. If he was born "on time", we might have had the same birthday (not birth date). Consequently, for a month every year, we are the same age. He currently lives in Fairfax, VA, and is the father of my niece, Alexandra.
Michael is brother #3. He currently lives in Fairfax, VA, too, but since he's also been stationed with the Coast Guard in Wilmington, NC, Puerto Rico, and Hawaii. He's the father of my nephew, John Michael, and my nieces Alyssa and Emily (my god-daughter).
Jay is my youngest brother, and he currently lives in San Diego, CA. No nieces or nephews via him. Yet.
In general, we all got along while we were growing up, and have gotten closer as we've gotten older.
And that's the Cliffs Notes version.
