Yes, I have 2 uncles born a day apart. My mother is also their baby sister, who was also born in September. I don’t know how their mother, my grandmother (who passed when my mom was 7 years old) did it with 5 children, 3 of whom were born in the same month?! I still remember the first time I left the state ALONE to visit Uncle Bobby by train. I hadn’t seen him since I was 6 years old and I was in high school, around my junior year, so needless to say, I walked right by him when I got off the train. He didn’t recognize me and I didn’t recognize him, but it became obvious once we were the only 2 left on the platform!
