HOLY COW!!! YES YES YES!!! That's my Aunt Doris! The only cousin I ever really knew was Dawn. You see, Gran being one of 10 and all 10 having anywhere from 1-5 kids, then you add their spouses, children and grandchildren and great grandchildren and you have anywhere from 200-300 people in your family! And yes, Uncle Jack is a total sweetie! I don't hardly ever see him. But I remember him coming to Gran's house soon before and after she died. We never left her alone and there were about 45 of us in the family then. But he and Uncle Charlie have always been the kindest and gentlest men we had in our family! So yes, by some dog-leg line we're distant "cousins" a bunch of times removed kinda sorta. 
I called my dad's sister, my Aunt Linda who was married to a Lawson for 35 years (had 2 kids Donna & Scott now ages 48 & 45) and she told me that yes, Smeltzer is Aunt Doris' maiden name. As far as Tom goes, we always called him Tommy even though he's about your age now. Old habit die hard. Shoot Scott still calls me Kimmy, Kimster, Kimmysue, whatever. And I'm 38! Frankly though, I still call him Skeeter, Skeets, Skeeter-eater, Skeetszo.
We can be a rather silly clan! 
Neat that you have great memories of the Scoreboard, too! I sure miss that place! Herndon sure isn't what it used to be!
So, nice to meet ya, cuz! 
This is grainey picture of the 1972 Arlington Trust Company Angels. Mom couldn't figure out how to work the scanner, so she faxed it. I cropped it a bit. That's your cousin Dale on the back left, your Uncle Jack on the back right, and that's me on the front right. I think Dale was 15, and I was 13. Well, I know I was 13.

One thing that is perhaps coincidental, but which you may want to take note if you didn't know - Dawn was diagnosed with Hodgkins when she was about 18 or 20. I remember when she was going through chemo, and often thought of them when reading the posts about Andrew. One day the regular doctor wasn't there, but a pediatrician was, so they gave her the child's dosage of the meds. She didn't get as sick, and, being small, they kept her on that dosage the rest of the way through the treatment. Like Andrew, she fully recovered, and has been doing great ever since.
Next time you hear from them, tell them Mike said hello. I'll probably stop by and see them when I'm up there for some Nats games in mid July. Actually, I'll get their phone number from mom & dad (they still talk a few times a year even though mom & dad moved away in 1993) and see if they'd like to go to a game, too.
This is all a very nice surprise!
One of my mom's brothers was named Skeeter. We just called him Skeez

I get lost in Herndon now. Last time I was there, I tried to get from the K-Mart center to our last home in Fairfax. I'm not certain of the street names, but I think the route was Van Buren/Foxmill/West Ox. I never even found Van Buren, and about a half hour later was still cruising through Herndon. I finally gave up, took Elden out of town to 50, and got there that way. I still miss it.
