I used to worry about carrying on my family's name-- one of my uncles wasn't married, and my other uncle showed no signs of having children, my father only had girl-childs. Sometime after my married uncle had a son, I realized I didn't have to throw away my maiden name if I didn't want, and even if I did, there were plenty of branches elsewhere. I have more extended cousins than I thought, even if they're somewhat trailer trashy for the most part.
