weird coincidence, or what's in a name?

I am friends and former colleagues with a very smart and capable lawyer who was born and raised in the Indian community in Malaysia. Which is quite extensive. She lived in London for a while before immigrating here about 25 years ago. She's ethnically Telugu, if I remember correctly. Anyway, her name is Meena Nachiappan. So imagine my surprise to receive a request to join my piano meetup group from a Meena Nachiappan, a young woman from Hillsboro, Oregon, complete with profile picture (not of the Meena I know). At first I thought it was some weird software glitch, but it's not. Turns out Nachiappan is fairly common among the Chettiar caste, and Meena, short for the goddess Meenakshi, is also a pretty common name. Both of them got a kick out of learning about the other.
