Among many other similarities between Pride and Prejudice and Bride and Prejudice is the obvious connections between names. Some of the parallel characters with similar/altered names are:Lalita = similar to Elizabeth Bennet's nickname, Lizzy; Jaya = Jane; Lahki = Lydia; Will Darcy = Fitzwilliam Darcy; Mr Kohli = Mr Collins. Wickham is still Wickham. Even Darcy's sister is named Georgie, as compared to Pride and Prejudice's Georgianna.
