Who is Angie Harmeyer from Project Princess and what is their importance?

The team is building a house for Angie Harmeyer and her family. Angie, her husband and two sons currently live in a trailer, and she is looking forward to the new house, especially because she is pregnant with her third child. She is so moved and excited about the house that she cries when the toilet flushes for the first time.

On Mia's final day in West Virginia, Angie complains of heartburn after both breakfast and lunch, and Mia suggests this may be contractions. Mia is right, and Angie gives birth later that day, naming her baby daughter Princess, in honor of Mia.
