Working on creating the surnames for a fantasy country. I want some sort of family naming system based off parental names, a bit like the "mac" often found in Scottish names. There are two examples from books I've read that keep popping into my mind. In Tamora Pierce's Wild Magic series, last names are based off of parents. So, the main character's last name is Sarrasri, because her mother's name was Sarra and "sri" is attached to the end of a female name. When the MC finds out who her father is, she realizes she can change her name to Weirynsra. Her father's name is Weiryn, and "sra" is added for a male name. I like this idea, but don't want to just rip it off, obviously. But I like the idea of adding an ending to the parent's name to make it the child's surname. Only issue there is that all characters last names will end the same way. Not sure I like that part. In Cinda Chima's seven Realms books, a prefix is added to the parent's first name. So Raisa (mom) and Han (dad) are the parents. Their daughter becomes Alyssa ana'Raisa and their son Adrian sul'Han. "ana" obviously being for girls and adding the female parent's name, "sul" being for boys and adding the male parent's name. I think I like the prefix idea better. I'm just having trouble coming up with my own system. My main character's name is Kaelie. Her mother's name is Rosalie. I want to do something using Rosalie's name (or a portion of it) as Kaelie's last name. But I am stuck. Ideas I've toyed with: Kaelie vai'Rosalie (makes me think German, too similar to "von") Kaelie vi'Rosalie (too many of the same-sounding endings, lol) ...and everything else I've tried in my head just sounds weird or dumb. Any ideas?
