Those names are very common in society, that's all, especially names like Sara, or Sarah. Oh, and EVEN Catherine, Kathy, Cathy and so on. I chose my name Catherine, for various reasons, I originally did make a list in my mind, so it was either Maria or Catherine. I chose Catherine, and at the time I wasn't sure why it was, I just felt more attracted to that name. My Mother's best friend was called Catherine, and she died of Cancer a long time ago. So that was a little bit of an 'Ouch' moment there. THEN, the day I told my mother, when I 'Came out' as it were, I later find out, from my sister, that I 'was' supposed to of been a girl, my mother, was planning to call her first born, 'Catherine'. So fact was she intended to originally call me Catherine all along, I never knew about it until many years later. So that really is 'spooky' to say the least. Who knew ? All I can say is some things are meant to happen.
