Family Name and Date Coincidences

Question:
I wanted to know the meaning behind a lot of coincidences with my partner. Both born the same year, my birthdate being May-11 and his Nov-5. I also wanted to include that his mother and my aunt have the exact same name, and my mother and his aunt have the exact same name, just different last names.

Answer: (Responses to questions rely on the accuracy of the name and birth date provided with the question. Typographical errors or incomplete information can result in an incorrect response.)
