Okay, first thing’s first, I thought his name was “Awesome” the first time I heard the Doctor say it and I am now disappointed that this future awesome person is not named Awesome. Love the name Orson, though, so I suppose it’s fine.
Anyways, let me get back to the theory. I’m sure I’m not the first person who thought about this, but it’s a theory that I’ve started to believe.
I think Orson Pink is connected to both the Doctor and Clara by blood.
Wait a second, let me explain.
The first Doctor’s companion was his granddaughter. In the Fourth Season of the reboot of Doctor Who, Jenny became a thing.
Danny Pink has some wibbly wobbly timey wimey stuff going around him.
The Doctor’s granddaughter, Susan Foreman, was one of the last Gallifreyan children born and married a man on earth named David Campbell. She had adopted three children (Ian, Barbara, and David Campbell Junior) and had one of her own: Alex Campbell. While Alex is confirmed to be dead, his mother is simply marked “lost”. It is unknown as to whether or not she is dead.
The Doctor’s “daughter” Jenny was seen to have the ability to regenerate at the end of her episode and went to explore the stars. From what the audience knows, she should be alive.
Both of these characters have the ability to time travel if they have the proper technology and are not, from what stands within the canon as of now, barren. Both have the potential of creating a family on earth that ties in with Dan’s, as well as Orson’s, family.
Now, for Clara. I believe that Clara is tied to Orson because the Doctor was able to find him in her timeline. Which possibly means that she will eventually end up with Dan. This may be too obvious and may just be a red herring in all this wibbly wobbly timey wimey stuff, but it’s a pretty decent possibility.
I believe, somewhere down the line, the Doctor is Dan’s and Orson’s Ancestor, and somewhere down the line, Clara is Orson’s ancestor.
