That's a really good timeline, MerryB!
There are a few things that I would correct, but I don't have documentation for. You could be right, but this also makes some sense to me. See what you think---
2010, CW and SW (then SK) meet. Not sure when they start living together.
In 2012, CW gets the job at the dealership in Colorado, prompting the move. From article quoted below, "Linda Biggers, a realtor who listed Shanann’s home, told The Daily Beast she believes the couple moved because Chris got a job out West."
According to the Daily Beast article, "Alore (their boss at the Ford Dealership in Colorado) said the Wattses moved to Colorado after Chris accepted a job as a mechanic at the dealership in 2012. Shanann was hired by the company’s internet sales department and, according to online reviews, was a talented salesperson."

So SW puts her house in NC up for sale. Remember that the real estate market was really bad at that time--it was close to the bottom of the market, and it may have taken a while for the house to sell. But according to the same article, "A deed for the house was signed in August 2012 while Shanann was living in Colorado, property records show."
Then they get married in November of that year in North Carolina. "Shannan King became Shanann Watts on Nov. 3, 2012. She and Chris married at the DoubleTree Suites by Hilton hotel in Charlotte, North Carolina." Same article.
Bella was born in December 2013, 13 months after they married.
