Grant also stated that Markle was never estranged from anyone in their family but Markle's schedule made it hard for her to always be around.
After just two dates on consecutive days in London in July a year ago, Prince Harry and Meghan Markle took what the prince characterized in their official engagement interview as a "huge leap"-they went on vacation together to Botswana".
However, it was his next comment that has caused a stir with Meghan's family back in the US.
Now, Meghan's brother, also called Thomas Markle, has told the Daily Mail that their father is "extremely hurtt" about the comments.
Grant stated that Markle always had a family and that didn't change even after the former Suits actress' parents, Thomas Markle and Doria Ragland, divorced.
"We'd get together on Christmases, on holidays, on birthdays, on Thanksgivings..." She was very privileged.
Meghan Markle and Prince Harry have more in common than a bond with Duchess Kate an a wedding engagement - they both love Botswana, too.

Kensington Palace also confirmed that Meghan will be giving up her charity work with the United Nations, plus her role as patron at organisations including World Vision Canada and One Young World.
In 2016 the actress revealed on her now defunct blog The Tig that she makes the same resolutions year after year.
She also tweeted: "Meg's family (our family) is complete with sister, brother, aunts, uncles, cousins, and the glue of our family, our awesome completely self-sacrificing father. Stop swearing. These make my New Year's resolution list almost (AKA actually every) single year", she wrote.
"Her engagement effectively spelt an end to her acting career so that was the final blow". She always did. Our dad is incredible and completely self sacrificing.
