This
If you took two random women and asked the odds of any particular coincidence, it's pretty unlikely.
For example, the chances of them sharing a birthday are 1/365.
However if you look to your entire group of aquaintences, the chances of any two people sharing a birthday rise rapidly. As that wikipedia page mentioned, it's 50% when the group numbers 23. I'm sure you know more people than that so it's almost certain you know a pair of people with matching birthdays.
Then factor in the fact that you didn't initially start off by wondering about your particular coincidence, but noticed it along the way. They could share initials instead or anything else.
The chances of you knowing two people who share some ridiculously unlikely coincidence is ridiculously likely, so long as you don't pick the people and the parameters a priori.
It's not widely known that probability and statistics are very interesting subjects.
