I like this concept, SnoopyFan, and have wondered about it for a long time.
I’m going to stay within the generation of my parents, their siblings, and their offspring. Aunts, uncles, cousins. Can’t do much in older generations except by hearsay.
Wordplay, fascination with puzzles and games. Great senses of humor, some of it dark and sardonic. Easy and glib conversation. Trivia hounds. The “did you know that…” sort of thing.
Musically, it’s a mixed bag. Some virtually tone deaf, but most can/could at least sing on key. Instruments range from piano (dominantly) to guitar, banjo, fiddle, drums, but, as best I can recall, nobody ever played professionally (unless you count playing for church services) or in organized musical groups like bands or orchestras.
Math abilities also wide-ranging, but I believe most could/can solve algebra problems with little strain. No geniuses, but at least one is a math professor at a college.
Writers and artists in the same basic category as musicians. Capable but not public about it. No pros, in other words.
Only a few real Mr. Fix-it types, though mostly capable of doing needed minor repairs. One uncle was a whiz and could build/fix anything he set his mind to.
In a few words generally: well-rounded, fun, entertaining, witty
