Are Sherlock and Star Trek’s Spock actually related?

The man from 221b Baker Street's legacy has lived long and prospered, but why do fans think he could be an ancestor of the Vulcan Starfleet Commander?


If there’s one thing Sherlock Holmes is known for it’s his logical approach to mystery solving and Benedict Cumberbatch’s Baker Street detective certainly lives up to that legacy.


In fact, he’s so logical that partner in (solving) crime John Watson wastes no time in comparing him to a very important Vulcan.

The reference may seem innocuous enough, but when you consider something Spock says in Star Trek VI: The Undiscovered Country, it suddenly becomes more significant.

“An ancestor of mine maintained that when you eliminate the impossible, whatever remains, however improbable, must be the truth”, he reveals in the film, before alternative timeline Spock cracks the quote out again (albeit without reference to an ancestor) in the 2009 Star Trek reboot.

Surely this means Spock is related to Sherlock, right?

Well, not necessarily.

They do love Sherlock Holmes in the Star Trek universe, but they tend to view him as a fictional character.

The Next Generation’s Data and Geordie even end up channeling him when they come together to solve Holmes-esque mysteries on the holodeck in “Elementary, Dear Data”. And they wind up with their very own Moriarty wreaking havoc on the starship Enterprise, too.

The fact that the character is portrayed as fictional doesn’t rule out the possibility that Spock and Sherlock share a familial connection though.

Who’s to say Spock’s ancestor isn’t Sherlock’s creator, Sir Arthur Conan Doyle?

The author appears to have made enough of an impression on the Star Trek Universe to warrant Starfleet naming one of their own ships after his iconic detective. The NCC-221B popped up on a call log in a blink and you’ll miss it moment.

And who’s to say the Sir Arthur Conan Doyle of the Star Trek Universe isn’t ACTUALLY Sherlock himself? It’s all fictional after all.

Regardless of the evidence, though, it sure is nice to sit behind out keyboards and imagine Sherlock as Vulcan marooned on earth.


His behaviour does makes the fan theory seem highly logical.
