What do you think of these names?

It really depends on what you want your readers to take away from the characters. A character's name needs to reflect the character and/or their addition to the plot. The most memorable characters are the ones in which their names and their important attributes are tied together (look at the memorable characters in Harry Potter for an example). Yes, the naming style should reflect the mother, but it's much more important to pick a name that reflects the character.
