You in particular, pretty low. But open up the names to be any first/last combo, and we have the Birthday Paradox.
My name is quite a bit more unique than Bartlett, and I still know of about a dozen people with the same first/last as myself. I thought about setting up an FB group named after us and inviting them all just for funsies. None of us are related as far as we can tell, but the name is unique enough that we probably are, if only distantly.
numerically, quite low, but given the number of people on the internet, it happens routinely. I'd guess most English speaking people have used <internet_search_of_choice> for their name and found duplicates So:
guess maybe 100 million English names on the internet, between 2 and 100 matches, so around 1 in 10 million
BTW. I got bored counting the matches for Jacob Bartlett on facebook. definitely more than 10
I've never met anyone (outside known relatives) with my spelling of surname. When I moved to my current UK city I was surprised to find a Firstname Lastname match in the same city.
Facebook shows dozens of the same name in the general area.
As I've seen some say, if you're one-in-a-million then there's ~7000 people like you out there somewhere!
Jacob and Bartlett are both relatively common names, I'd say aggregating over a lifetime one can expect to coincidentially bump into quite a few over the years (since the advent of the internet at least!)
