In order to help distribute ages more fluidly, I'm going to be posting and frequently updating this list. Since certain years and houses tend to get a bit hefty, hopefully this will even it out.
There should be no more than six per gender per house per year. Meaning there can be six gryffindor girls from 1978, and then you have to pick another year or another house. This is to make sure we don't end up with an unrealistic number of people in one year, and none in another. Currently, every gender is still open in every house and every year.
