It's not really an uncommon occurrence. I have met many women who were the youngest sister to an all male family and they were all self-described tomboys growing up.

Younger siblings tend to mimic what the older siblings do. If you're the youngest (and only) girl in the family and your older siblings are all boys, if you're going to want to fit in with them, you have to do what they like.
