Where does Richmond, in Shakespeare's Richard III, come from?

Question:

Where does Richmond, in Shakespeare's Richard III, come from?

Richmond, not Richard.

I think they mentioned that Richmond was coming from this place to attack Richard to get the throne, but I've forgotten where.

Thanks.

Thanks for the info about the real Richmond, but I need it in the context of the play. :)
