Both of those last names are fairly common, and a college has a high population and a high density, so they're more likely to meet. Still, it's a tad unlikely, but it's a world wide web. Weirder things have actually happened.
A friend of mine (she has a quite uncommon name) discovered that another girl with exactly the same name lives in the same city, goes to the same university, visits the same gynecologist and the same physio therapist as her.
She knows because there always were complications with her name in those places.
