Three reasons for my username:
1) Brown is my last name
2) My grandfather was a blacksmith and inventor of the "Brownie" Chain Tightener (so named because it was small and helpful, like the brownies in children's stories). When he incorporated his company in 1942, he called it Brownie Manufacturing Co, Inc. I worked for the company for 10-1/2 years, and everyone in the family was called "Brownie". Although my father never worked for the company, there were so many Bob's of his generation, that everyone called him Brownie to avoid confusion.
3) When it came time to select my user name for this site, I thought about my TT & TV both being brown, my dog being brown (& white), reasons 1 & 2, and it just seemed right.
