Planning a dinner

I'm planning a dinner party, not in real life, but for a Regency novel I'm writing. I'm not sure how to make the seating arrangement and here are some good tips from Annette who searches for more Regency information for me:

guests were not assigned seats, but it was by chance

it was bad manners for a woman to help herself so unless the servants were serving, there had to be at least one man per two women

Jane Austen for Dummies said there was an order of entry into the dining room.

Aristocracy (titled first, non titled second)

Titled commoners and their offspring

Married women before Single women

Most distinguished woman to the right of the host and most distinguished man to the right of the hostess
