Here is some more background on the 36-year-old Castro, according to her website:

"Being raised in a very religious household, Dolly’s parents were also very firm on making sure education was a key factor in her life, and something she pursued. Wanting to become a chef was a dream for Dolly, however a career as a lawyer was a much more respected profession in her fathers eyes and that’s exactly what she studied for 9 semesters.

"The birth of a child gave Dolly such joy, it was a sense of fulfillment. Having someone to take care of and be a positive role model for immediately became a priority for her and she wanted nothing more than to make sure her beautiful daughter had an amazing life."
