Jamie has a son named William Ransom with Geneva Dunsany, who died during William's birth. Jamie also has two stepdaughters, Marsali MacKimmie Fraser and Joan MacKimmie, from his marriage to his second wife, Laoghaire MacKenzie.
Nonetheless, Jamie did have sexual relations with Laoghaire in a bid to make the marriage work but ultimately failed and so the couple separated. Additionally, it seems Jamie was acting of out duty to his new wife however past trauma meant Laoghaire was unable to reciprocate.
The writers of Outlander made a big change to the series from the source material in season three. In the third outing, Jamie Fraser (played by Sam Heughan) tied the knot with Laoghaire MacKenzie (Nell Hudson) during the 20 years while Claire (Caitriona Balfe) was in the future.
There are no biological children after Brianna in Outlander
Claire and Jamie don't have any more children after Brianna. Claire heads through the stones while pregnant with Brianna at the end of the second season/book. She spends 20 years in the 20th century, and she and Frank don't have any children together.
Season(s) Geneva Dunsany was the daughter of Lord and Lady Dunsany, who reside at the Helwater estate. She blackmailed Jamie Fraser into a one-night stand, which resulted in their illegitimate child, William Ransom.
Jamie has a son named William Ransom with Geneva Dunsany, who died during William's birth. Jamie also has two stepdaughters, Marsali MacKimmie Fraser and Joan MacKimmie, from his marriage to his second wife, Laoghaire MacKenzie.
Just as she begins to worry that Jamie might be capable of lying to her, Jamie quells her fear by revealing to her his indiscretion with Mary MacNab, a woman who worked at Lallybroch, while Claire was back in 1968 with Frank and Brianna. This confession soothes Claire, and the two find themselves realigned once again.
Claire Meets Jamie's Son and Saves Lord John Grey on Outlander - Outlander Season 4 Episode 6.
When Claire returns to the past, she and Jamie reconnect and begin to live as man and wife once again. But some might be wondering what the legal implications of Jamie's marriage to Laoghaire might mean. Given he remarried after Claire, it seems possible their marriage might be void after all.
Claire gives him a beautiful, tender answer: she shares his regret, but regret is not enough. And together they make the decision to give the baby to Lucinda, a young mother who lost her own baby at birth, and has both love and milk in abundance.
Unable to sleep, Claire heads to Colum's library to borrow a book, and ends up eavesdropping on a conversation between Colum and Dougal. She discerns that Dougal has gotten Laoghaire pregnant.
This one stings.
Outlander fans were left devastated after couple Jamie and Claire were forced apart by historical events at the end of season two. Claire went back through the stones and to the 20th century where she was reunited with her first husband Frank Randall (Tobias Menzies).
Laoghaire goes completely nuts. She tells Brianna her mother is a witch who should have burned at the stake, that she bewitched Jamie and nastily tells her that Jamie never wanted a child, so he sent Claire away. She locks Brianna up.
Jamie does admit he's slept with someone else, telling her about his one-night tryst with Mary MacNab (Emma Campbell-Jones) before he turned himself in to authorities following the Battle of Culloden nearly 20 years prior.
Some think Jamie's spirit (but not his body) traveled to through time to guide Claire to him; others suggest Jamie had a near-death experience after the Battle of Culloden, and that's why his ghost is 25 when he appears to Frank.
Did you guess Lord John Grey? Because yes, Claire and Lord John end up married in book seven, and yes, they drunkenly (and full of grief for the loss of Jamie, whom they both love with all of their heart) consummate that marriage.
For instance, Lord John Grey learns the truth about Claire, Brianna, and Roger... though he has a hard time believing it. And speaking of Roger and Brianna, they get into their own time-travel trouble — Roger with his ancestor Buck and Brianna with Rob Cameron.
Since the age of six, William has been raised by Lord John Grey, his legal guardian and husband of Geneva's younger sister, Isobel Dunsany.
While Brianna knows who William is, William does not yet know that Jamie is his father and that Brianna is his sister. He doesn't discover the connection until late in book seven, when he finds himself in Jamie's company and finally sees the resemblance between them.
Jamie's Secret is a story about a nine-year-old who loves soccer, playing with her best friend Sadie, and collecting crystals. She loves hugging and climbing trees, watching butterflies, and soaring on her swing. Jamie loves life and everything that points to it.
Claire Saves Jamie's Life by Giving Him a [NSFW] in Outlander Season 5, Episode 9. Forget CPR! So, this entire episode of Outlander basically revolved around an evil snake (Lord Voldemort, is that you?) biting Jamie's thigh, and it was all extremely dramatic and angsty so let's get right to it.
Director Brendan Maher told Vulture that while both Menzies and Heughan had stunt doubles for the physically demanding sequence, neither used them much. “We had people for safety, just in case, but the nature of the work is that you want the actors to do as much as they possibly can,” Maher said.
Jamie: "Claire, it was you. It's always been you, and it always will be. Get into bed and put the candle out.
