Meghan Markle is class, kindness, style, generosity and inspiration personified. She was raised by both of her parents to embrace who she is and to embrace life, and also to create her own identity and not allow others to label her. She's a very together person.
I think in part Meghan gets her caring heart and kindness from her mother (who is a social worker and a yoga instructor). From her father, Meghan appears to have gained her interest in the acting profession. Meghan has mentioned being nurtured, supported and encouraged by both of her parents. Despite the fact that her parents divorced when she was very young, they remained on the same page about giving their daughter the best of everything, which breeds confidence and a sense of purpose. Meghan has got loads of both.
Meghan indicates that her parents share a love of antiques and that they would join together in taking her on vacations when she was growing up. So, apparently Meghan did not experience much angst as a child of divorce, unlike Diana, Princess of Wales, and indeed Princes Harry and William too. So kudos to Meghan's parents in that and in many other respects.
To the poster who mentioned Meghan's father's ancestry. I read that it's Dutch-Irish. Her mother's white ancestors may hail from England and/or Scotland, possibly Ireland. I'm sure we will find out in more detail once an engagement is announced.
As far as Meghan having ancestors who were slaves, if we go back far enough, we're likely to find that slavery and/or indentured servitude existed in quite a few families throughout the history of mankind. And we know how hard slaves worked and how much they had to overcome just to survive. It also pays to remember that all of the labels and divisions we bandy about casually are man-made separations, which have no bearing on the reality of human evolution. Interestingly, the wife of King George III (Sophie Charlotte of Mecklenburg-Strelitz) is said to have had African ancestry on her mother's side via Portuguese ancestors -- unsurprising since the Moors ruled Spain, Portugal and other parts of Europe in ancient times.
Back to Meghan. There's not a 'vulgar' bone in her body. So we should probably put that to rest and focus on Meghan and Harry. With the revelation that Meghan declined to renew her contract with Reitmans last December, it seems to me that there is a lot going on behind-the-scenes with preparations for an engagement and an eventual marriage. And, as other posters have speculated, Meghan & Harry appear to have already made a very serious commitment to each other privately.
I can't see any scenario where Meghan would be abruptly and completely giving up lucrative projects like her lifestyle blog and her contract with Reitmans if she and Harry were not planning on staying in their relationship for keeps. In other words,
I'm betting Harry can hardly wait to put a ring on it!
