One Ontario man thought the engagement was good news for another minority: the ginger haired.
After news that Prince Harry had sought permission from Ms Markle’s father, it was then the turn of Wendell Pierce, who plays her on-screen father in the TV drama Suits, to add his blessing.
Patrick Adams, who plays her love interest in the drama, also joked about it.
Ms Markle will now find herself rubbing shoulders with the great and good of British high society.
It is an experience familiar to the American nutritionist and author, and now Viscountess Hinchingbrooke, Julie Montagu.
Ms Montagu, from Sugar Grove, Illinois, married John Montagu, the 11th Earl of Sandwich.
“It about being respectful of the history, the history Megan is marrying into is older than America itself,” she told the BBC. “At the same time, you don’t want to lose who you are a a person and as an American.”
She said Ms Markle might face a steep learning curve when it came to pronunciation (“My first lesson was that ‘viscount’ doesn’t rhyme with ‘discount'”) and setting a table (“All those forks and knives and spoons… I had to have my husband show me how to set a table”).
It would however be “such a breath of fresh air to have an American”, she said.
UK social media site Joe.co.uk won some fans for taking a slightly different perspective to most, by making the successful bride-to-be the focus of the news.
Twitchy.com editor Greg Pollowitz also speculated that it might be part of an elaborate ploy to take back America.
Prince Harry’s kids will be Americans. What if one grows up to be president and is in line for the throne at the same time? Brits are playing long-ball here, but it’s a smart move. They want America back and this is how they’ll do it.
On another note, Twitter-shy US president Donald Trump has yet to offer his congratulations to the couple. Canadian prime minister Justin Trudeau has.
Natasha Bird, digital editor at Elle Magazine, which has published two essays by Ms Markle, speculated that the American actress might help Her Majesty’s subjects “lose a bit of our British cynicism and adopt more of the we-can-do-anything attitude they have in America”.
Good luck to her.
