Doctor Who 28493

Tomorrow's the 50th anniversary of one of sci-fi's most beloved characters—the time-traveling, two-hearted Doctor Who. We'll be celebrating it big time in our house, with British-y food (including Jelly Babies, if I can find them), and watching the special "Day of the Doctor" show.

The good Doctor's name still remains under wraps, 50 years later—only his wife apparently knows what it is. But if you do a little trolling amongst the Doctors many companions through the years, you'll find some cool names that might be worth considering.

Clara Oswald is the Doctor's current companion, and has a bit of an odd past, having popped up in the series and died a few different times before signing on as a companion. Clara means bright, and is on a big run for the top right now, nearing the top 100 baby names in the U.S.

Rose Tyler is likely my favorite companion, and the first of the modern-era companions. A plucky former shopgirl, she helped the Doctor save the world—a lot. Her pretty floral name has become red hot over the past three years, and is currently at #261 in the U.S.

Sarah-Jane Smith was the Fourth Doctor's companion (you know, the one with the funky striped scarf). She's often held up as the most beloved of the Doctor's companions, and even launched her own spinoff, The Sarah-Jane Chronicles. I'm intrigued by the hyphenated first name, combining two ultraclassic names—the Biblical Sarah, which means princess, and the stately Jane, which means God's gift.

Amy Pond's official name is the uberpopular Amelia. This spunky redhead traveled with the 11th Doctor and her future husband—and (spoiler alert!) gave birth to the Doctor's wife. Amelia means "work."

Rory Williams was Amy Pond's true love and mate, who followed his Scottish lass through a very convoluted timeline in the Doctor's TARDIS. His Irish name means red king, and is currently in the top 500 baby names for boys.

Captain Jack Harkness was one of the coolest characters on the new series—a bit of a smarmy and brash American time traveler, who flirted with anyone who walked. Jack's a top name in the UK, and in the top 50 here in the U.S., and is a variation of John.

Wilfred Mott is the grandfather of one of the Tenth Doctor's companions, Donna Noble, and he went on to travel with the Doctor himself. His name, which means "desires peace," fell out of the top 1000 nearly a half century ago, but this name offers two red-hot nicknames—Will and Freddie—in one.

River Song is the name of the Doctor's wife, who can travel through time and definitely keep the brilliant Doc on his toes. River is just starting to become popular for girls, but it's a lovely name (especially combined with Song!).

Tegan Jovanka was one of the longest running companions, traveling with the Fourth and Fifth Doctors. Her name is a modern invention, and has only been in the top 1000 names for 2010 and 2011.

Martha Jones was very nearly a doctor (though a more mundane kind) in her own right—she's a med student who traveled with the 10th Doctor. Her name means "lady," and is in the top 800 baby names here in the U.S.
