name games

Mrs. Marmeladov's name is Katherina Ivanova.

Katherina Ivanova is also the name of one of the heroines in Brothers Karamazov; she was very proud and had an awful temper, though she could be tender when she wanted to be; and she wasn't low-born.

Both Katherina Ivanovas share these basic characteristics. When I read Brothers Karamazov, I thought that Katherina was likely to end up going crazy if she didn't get herself and her ungovernable passions under control.

My question is,

Was were both Katherinas the same woman,
were they different but Dostoevsky was trying to make a point,
or did Dostoevsky just like the name and forgot he already used it?

Considering that one was miserable wife of a penniless vodka fan and the other one rich and respected - I doubt.
