1.) Lottie is an Amy. She was actually a lot like Amy when she was a child - petted because she's the youngest, was always trying to be more mature than she actually was, concerned about being as pretty as her sisters one day, etc. Now that she's older, Lottie has grown out of her "petted" stage and her maturity has devolved into a pragmatic sense in which she knows that a good marriage could help her achieve her goals without having to rely on her parents financially.

2.) Cassia is a Beth. She's also shy and at the moment doesn't have too many ambitions (that she knows of yet though Miri has ~plans~) besides getting through school and focusing on her friends and family. She's also inadvertently become the peacemaker between Cordelia and the people Cora has upset. xD

3.) Veronica is a mixture between Meg and Beth. Like Meg, Veronica might have once had childhood dreams but they were just that - childhood dreams, so when she grew up she became a wife and mother because she knew that that's where her strengths lied. Unlike Meg, however, and more similarly to Beth, she does not like being the center of attention and enjoys being at home.
