I need some help with names, does anyone have some ideas?

I was planning on menulis a story about six sisters living in the 1970's with poor, abusive parents, here are the characters;

15--long light brown hair, big blue/green eyes, tan, very pretty
14--short curly black hair, small blue eyes, glasses, freckles, fair, dimples
8--Long curly blonde hair, green eyes, fair skin, dimples, short for her age
4--Shoulderlength light brown hair, big/blue green eyes, fair skin, rosy cheeks, dimples (looks a lot like her 16-year-old sister)
18 months--Some brownish hair, blue eyes, fair skin, chubby, adorable
3 months--Bald baby, big blue eyes, rosy cheeks, a beautiful baby!

Now here are the three main things that describes each character;
15-year-old is kind, compassionate, maternal
14-year-old is shy, jealous of her older sister, intelligent
8-year-old is loud, annoying, clingy
4-year-old is bubbly, jubilant, adventurous
18-month-old is cranky, cute, and loves to say new words.
3-month-old pretty much sleeps a lot and loves to play with her fingers and feet..

I was planning on having their names all start with the letter B.

The 3-month-old baby may be the hardest to name, so I diposting a pic that fits my keterangan so anda could name her mor easily ^_^

Any suggestions? :)
