Once in awhile I have even given my hero and heroine a birth month based on the characteristics portrayed and which astrology sign makes that most likely. For those of you with no interest or knowledge of astrology, you might be surprised how often the time when one is born can tell a lot about natural traits. The reason for that is not clear to me, but just I have often seen it to be so. Do not confuse a birth chart with horoscopes.
Below is an example of one from my Arizona historical character lists. It has been added onto as books were written and characters added. When I start writing any book, I add in the new characters and their births-- maybe even deaths of some older people-- death is part of life unwilling as we are to see it come to those we love.
I have had some reservations about sharing with readers these character lists mainly because if a reader hasn't read the books, the list gives away what will happen. Of course, romance readers already know a HEA is guaranteed. For those of you who don't read my books, this is mostly to give you an idea of what you can do if you ever decide to write stories that follow a family through many years. As the little image says, these books go from 1883 to 1906 or will go to 1906 when the last one is out.
On this list, some of these characters never became more than secondary ones but when putting together a character list, it's better to add them in case somewhere down the line, they get their own book. It happens. I do a second such list that has the basics of each major character in any book I am writing. This doesn't require birth dates but personalities and interactions. Some call this kind of information the bible as such are done for screen plays.
