Joining their tribe, Ian found love with a Mohawk woman, Emily, and the pair were married. Shortly thereafter, Emily got pregnant but lost the child—a tragic pattern that then repeated.
As Ian grieved, he was told to leave the Mohawk tribe. They believed the man's spirit must battle with the woman's and overcome it, but sadly, the Mohawk tribe felt Ian's spirit was not strong enough for a child to take root in the womb and therefore, he and Emily were no longer compatible.
He was clearly depressed. And while out surveying the Ridge's land with Roger, Ian came close to attempting suicide with Claire's Water Hemlock. Roger stopped him before he could ingest it in a tea. Ian eventually reveals he got married while living with the Mohawk.
After several miscarriages, Young Ian left his wife and the tribe on the advice of Emily's grandmother. In the source material, he later went back to find Emily had re-married and had children with her new husband.
Later, after Claire has returned to the Ridge, she is confessor to Allan Christie, who explains that he was the one that fathered Malva's child, and then murdered her.
The killer is in fact Malva's brother, Allan Christie (Alexander Vlahos). He is also the father of her baby, having raped and abused Malva since she was a child. Malva had decided to tell the truth, which is why Allan killed her.
The baby didn't survive. After that, Emily got pregnant again. This time, she suffered a miscarriage.
After losing two children, Emily left Ian and chose Kaheroton as her partner — and Ian was ostracized from his tribe. Ian confessed all this to Jamie, and Jamie spoke of Faith, the daughter he lost in Paris with Claire (Caitriona Balfe) so many years ago.
However, Young Ian turned to Claire with a confession. The baby could be his. It turns out Ian and Malva did sleep together.
But you can't deny that he did spend three, four years with the Mohawk. He will never lose that part of his history and he will always carry that with him. He's fierce because of it. He proved to himself, I think, that he could survive without Jamie, without any of his family.
In the novels, Marsali and Fergus apparently know. They haven't been told on-page, but Diana Gabaldon confirms that the two know that Claire, Bree, and Roger are time travelers.
Janet "Jenny" Fraser Murray: Jamie's older sister, and only living sibling. She is married to Ian Murray and has seven children.
Claire eventually realizes that Malva is lying because she knows her husband well enough. Tom seems to question Malva's story. You can see it in his face that he's trying to figure out if this story is true. And then there are the reactions at the funeral when Allan refuses to let Claire carry the baby's coffin out.
Malva Christie might have only been introduced in Outlander Season 6, but she has a central role in the drama. The daughter of Tom Christie, she is both naive and sinister, and many Outlander fans have struggled to work out her true intentions.
Claire knows that she didn't have the same thing, but she can't get to the bottom of the cause. It's Tom who eventually finds out. Malva, before her death, tells him that she made them sick. She'd collected parts of the dead Sin Eater and poisoned Claire and Tom.
In addition to having Claire, Jamie, and Bree, he cultivates a friendship with “mountain man” John Quincy Myers, who is friendly with the local indigenous population. At the end of Season 4, Ian agrees to stay with the Mohawk Tribe in exchange for Roger's freedom, a decision he sees as a new adventure.
Ian and Rachel then come to Lord John Grey's house, where Ian is reunited with his mother Jenny Murray. Rachel and Ian marry in Philadelphia in late July/early August. In late spring 1779, Ian returns to the Fraser's Ridge in North Carolina, bringing his pregnant wife Rachel with him.
Young Ian's Assault
Young Ian is kidnapped by pirates of the Bruja ship where he is taken to a time traveler, Geillis Duncan. Geillis has kidnapped many young boys other than Ian. Once she got the information she needed from Ian, she drugged and raped him.
She is married to Ian Murray and together they have seven children.
In “A Breath and Snow and Ashes,” Young Ian eventually tells Marsali and Brianna the story of what happened. He and his wife, Emily, tried to start a family. However, the two couldn't have children together. Every child they had was either stillborn or Emily miscarried.
Jamie denies having slept with her, but the damage to his and to Claire's reputation is done—and the bond between the Frasers and Malva is severed, until just a few weeks later, when Claire finds Malva murdered in the garden.
The haircutting was part of the process. Malva wanted to make Claire undesirable. She wanted to make Jamie turn to her instead of to his wife. We can get a sense of that from the way Claire worried about Jamie seeing her with the short, jagged hair.
She's never seemed curious about the intimacies of a couple before. This suggests that she's up to something. Watching the two gives her information to use in the future.
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.
Tom confesses to Malva's murder and tells Claire that the strange sickness he shared with Claire seen at the beginning of Outlander season 6, episode 6 was Malva's attempt to murder them both.
