Your simple answer is Charles Lee.

You see, there are two possible birth dates, 1753, and 1755. The thing is, 1755 was on the Connor bio, but got pulled, and Charles Lee had two twins to a Native American from the Mohawk.

Now, we have seen Charles Lee with Connor before, add in all of that....

CHARLES LEE.

The game starts at 1753 tho, what could we do for those 2 years? you see, Connor's Native American name means Scratcher of Life, could mean he had a hard birth, so Desmond had to sync with his Charles Lee/The mother of Connor for 2 years before being able to get into Connor.
