If you make the life-changing decision to get married, it's important to remember you're not only promising to spend your life with your partner, but also in some ways their family too.
For Meghan Markle and Prince Harry - who are rumoured to be hearing wedding bells already - the possibility of marriage will undoubtedly bring them a wealth of unwanted public scrutiny, paparazzi attention and affect the actress' career forever.
After all, not every bride will have the Queen of England for a grandmother-in-law.
But, while we know everything there is to know about Prince Harry's family, we thought it was about time we learned a little bit more about the Hazza's potential future in-laws - Tom Markle and Doria Radlan.
Here's everything you need to know about Meghan Markle's parents:
Meghan's mother: Dorian Radlan
1. She's a social worker and yoga instructor
Earlier this summer, Markle explained to Glamour that her mother 'works specifically with the geriatric community'.
A self-proclaimed yoga-lover, Markle has previously admitted she has developed a skill for the fitness regime from her mother.
'My mom was a yoga instructor so that practice is in my blood,' she told Women's Health. 'I love an intense vinyasa class - and even better if its blasting hip-hop and done in a dark room with candlelight.'
2. She's got a nose piercing
'My mom has always been a free spirit. She's got dreadlocks and a nose ring,' the Suits actress told Glamour.
'She just ran the LA marathon. We can just have so much fun together, and yet I'll still find so much solace in her support. That duality coexists the same way it would in a best friend.'
3. Doria divorced Meghan's father when the star was six-years-old
In 2015, Meghan penned an emotional letter for ELLE UK titled 'I'm More Than An Other' discussing her biracial identity and talked about how her parents met.
'It was the late Seventies when my parents met, my dad was a lighting director for a soap opera and my mom was a temp at the studio,' she wrote.
'I like to think he was drawn to her sweet eyes and her Afro, plus their shared love of antiques. Whatever it was, they married and had me,' she added.
Sadly, they split when Meghan was a child.
4. Her nickname for Meghan is 'flower'
In her now defunct lifestyle blog, The Tig, Meghan explained her nicknames range from 'Meg, MM, M&M' and revealed her mother calls her 'Flower,' 'which my mum has called me since I was little'.
Meanwhile, in a post to Instagram last year to celebrate Father's Day, Meghan signed off her post with the nickname 'Bean'.
5. She warns Markle of wearing too many skin-tight outfits
The Telegraph revealed the yoga instructor always told her daughter 'never give the milk away for free'.
6. Her ancestors were slaves in the US
In her essay for ELLE UK, the actress explained that in 1865 when slavery was abolished in the United States, former slaves had to choose their own surname and her great-great-great grandfather called himself 'Wisdom'.
'He drew his own box,' he added.
Meghan's father: Tom Markle
1. He's a former television lighting director
On The Tig, the 36-year-old wrote: 'My father was the lighting director on two television shows as I was growing up.
'And there I was, behind the scenes of a glossy soap opera and a TV sitcom, surrounded by famous actors and their glam teams, multi-million dollar budgets, and crew lunches that always included filet mignon and enough sweets to make you think you were at Willy Wonka's Chocolate Factory.'
2. He taught his daughter to define her own identity
Following a devastating moment at school when her teacher told her to check the box for Caucasian on a mandatory census, leaving her to leave the box blank in confusion, Markle wrote in ELLE UK that her father told her: 'If that happens again, you draw your own box.'
'I never saw my father angry, but in that moment I could see the blotchiness of his skin crawling from pink to red. It made the green of his eyes pop and his brow was weighted at the thought of his daughter being prey to ignorance. Growing up in a homogeneous community in Pennsylvania, the concept of marrying an African-American woman was not on the cards for my dad.'
3. He father is an Award-winner
The Express reports Tom won a Daytime Emmy Award for Outstanding Achievement in Design Excellence For A Daytime Drama Series.
4. He has already met Prince Harry
Like Doria, who was spotted chatting with Prince Harry at the Invictus Games over the weekend, Tom has met Prince Harry and is said to be 'pretty happy' about his daughter's relationship with the royal.
Earlier this year, Meghan's half-brother Thomas Markle Jr told the Daily Mail: 'He first met Prince Harry about six months ago out in Toronto.
'He's pretty happy about Harry and he's extremely proud of her. They have an amazing relationship, they're very close and they always have been.'
