- The Duchess of Sussex met her 'cousin', Red Sox outfielder Mookie Betts at the London Stadium tonight
- The pair are said to have relatives dating back 150 years to Alabama and shared a hug with each other
- The Duke and Duchess of Sussex were also given little Red Sox and Yankee jerseys for royal baby Archie
- Europe's first ever Major League Baseball game will take place between the Boston and New York sides
- Prince Harry's Invictus Games Foundation has been partnered with the MLB for the historic London Series
- Former Invictus games competitors from the USA and the UK will throw the first ceremonial pitch
The Duchess of Sussex shared a hug with her 'cousin' Boston Red Sox's Mookie Betts as she and Prince Harry met players ahead of their game against the New York Yankees in London.
As Europe's first ever Major League Baseball game was given the royal stamp of approval, family history may have also been made as Meghan met award-winning outfielder Betts at Queen Elizabeth Olympic Park tonight.
Meghan and Betts reportedly share ancestry dating back 150 years to America's deep south, according to a U.S. genealogist, who says both their origins can be traced back to Alabama relatives.
The royal couple are attending to promote Prince Harry's Invictus Games Foundation which has been partnered with the MLB's two-game London Series.
Betts told the Boston Globe last year: 'I saw on television that they were getting married. But I had no idea we were related ... That's not something you expect to hear, but it’s interesting.'
An 1870 Federal Consensus reportedly shows that Joseph Betts is Mookie's great-great grandfather and Jacob Betts - who lived two doors down from Joseph - is the great-great-great grandfather of Meghan.
Genealogist Jim McNiff, who uncovered the link, believes the chances of coincidence are minimal due to the scarcity of Betts' in Madison County and the proximity of the neighbours.
Meghan and Betts were seen hugging this evening in the Red Sox locker room, as Prince Harry and the players clapped and laughed.
Meghan beamed as each team gave her a baby-sized jersey, with the New York Yankees shirt emblazoned with Archie's name and the number 19 on the back for the year of his birth.
Former Invictus athletes from the USA and the UK will take part in throwing the ceremonial first pitch at the London stadium which is home to Premier League football club West Ham United.
The Invictus foundation was founded by Prince Harry for wounded, sick and injured armed service personnel to take part in various sporting events.
There is a sell-out crowd tonight as the baseball rivals take each other on before some 66,000 spectators, with the Yankees and the Red Sox competing in the AL East conference.
Similar in style to the British sports of rounders, this is the first time America's colossal MLB has attempted to sell itself in the UK.
With some of the MLB's 30 teams having previously played in Mexico, Japan, Australia, and Puerto Rico, it's believed chiefs at the organisation are keen to make their mark in an untapped market.
But it comes over a decade after the NFL made its debut appearance at London's Wembley Stadium with a match between the Miami Dolphins and the New York Giants.
Because of the need for a larger, more circular pitch the organisation has picked the London Stadium to host the inaugural meet.
The former Olympic stadium, where West Ham play their home games, is hosting two games between the New York Yankees and Boston Red Sox this Saturday and Sunday.
