We're flying up to Detroit this evening, and then driving up to Houghton Lake, Michigan, for the wedding of a second cousin (or is it first cousin, once removed? Whatever the daughter of a first cousin would be...).

Don't know if I'll have Internet this weekend, or time to post. Sunday night I'll be down in Ann Arbor, where I will have Internet (though possibly still no time). Anyway, I'll be back Tuesday morning, when things should start to get back to normal, except things are very busy in general, as its SBIR season for NASA, and I'm busy writing proposals due the first week of September.

First cousin once removed.
Each removal can be viewed as a half generation.
Your children would be her second cousins.
However those "half generations" only add up for the same generation. Her children would be your first cousins twice removed.

First Keith Cowing leaves for "Haughton Crater". Not long after, Rand Simberg disappears to "Houghton Lake".

"All across the country, space bloggers disappeared with similar stories. And once again, the Rice Hotel starts filling up with people named "Max Peck"...."

Soccer Dad beat me to it. It was using the old DOS version of Brother's Keeper that taught me the distinctions years ago.

Nth cousin is someone in the same generation.

Nth cousin Xth removed is in a different generation.

In my family there are such wide spreads in when people had kids and at what ages, there's a lot of funny mismatches. My grandniece is two months older than my oldest daughter. Since my oldest nephew, said grandniece's father, a year older than my wife, who is 13 years younger than me, is my daughter's first cousin, the grandniece is my daughter's first cousin once removed.

By contrast, my cousin, born within a month of my wife, has a baby in between the ages of my two daughters, another contemporary. She and my daughters are the same generation, the children of first cousins, and so they are second cousins. Whereas my cousin and my daughters are first cousins once removed to each other.

My cousin's daughter is a second cousin to my nephew. That means to my grandnieces, my cousin's daughter is second cousin once removed, being effectively one generation apart via second cousins.

By being verbose, I probably just made it seem more complicated...

Ah, but which moiety is that? Did she have to change ships to get married at the Gathering of Free Traders?

(Brownie point to anyone who can isolate the reference...)
