Name help, please!

So! Long story short, I have a friend who's started playing Dungeons and Dragons. I'm excited because I've wanted to play for forever (or like 5 years). I'm going to ask her if her group is accepting new people, which I believe it is. (If not, I'll look for another group. I know there are more than a few in the area.) I don't want to be completely clueless, so I've been researching the game a lot and creating practice/preliminary character sheets. 

So far, I have a lightfoot halfling sorcerer named Cela Gedri. I've been working a little on a background, because I love those. I've decided that she has 5 older sisters (ranging from 11-17 years older than her). The problem lies in naming all of them. I decided to create a list of short names that are related to other halfling names I've researched. 

tl;dr Need 5 names. Either from this list or similar to this list. 

Ada
Adie
Ande
Beda

Marga
Nika
Onda
Osma
Tansy

Thanks!
