I found this on the web and thought it might come in handy:

 Character Background:

FAMILY BACKGROUND:
~~~~~~~~~~~~~~~~~~~

Your family background can be as long as you want, but it will need to
have these specific things at least:

1. What your family DOES to maintain its status. This can be
merchanting, land ownership, fighting wars, etc. Whatever your
family is particularly known for being good at.

2. Where YOU stand with your family, and how you fit into the family tree.

3. A description of your family’s general personality. Are you known
to be hot-headed people? or particularly untrustworthy?

CHARACTER BACKGROUND:
~~~~~~~~~~~~~~~~~~~~~~~~

Your character background can also be as long or short as you want,
but it needs to have at least the following things:

1. Your personal history (a rough timeline is ok)

2. Where you currently reside

3. How you gained whatever good or bad personal influence you currently have.

CHARACTER PERSONALITY:
~~~~~~~~~~~~~~~~~~~~~~~

This needs to include your character’s motivations, goals, strengths,
and weaknesses. How does he feel about royalty in general? how does he
react to sudden change? How does he treat servants, and what is his
daily life like? What does your character want? I would like a broad
overview, so that I can accurately judge how you respond to issues
that will arise during the game. it is imperative that you play your
character along the lines you list here.
