My cousin was born on New Years eve.
Our grandpa was born on Christmas. Our grandpa shared his b-day with 2 sisters all 3 born on the same day in different years.
This same grandpa had a little girl, my mother, born on the 4th of July.
My mom had my brother on Christmas.
This same brother had my niece on Thanksgiving.
Me, well its not a holiday but I haven't heard of anyone else graduating from high school on their b-day.
