When Brianna travels to 18th-century Scotland, she marries Roger MacKenzie. They have a son, Jeremiah "Jemmy" Fraser MacKenzie, and a daughter, Amanda MacKenzie.
It turns out that they do have another baby. It's some time while they're in the past, and they name their new son David William Ian Fraser MacKenzie. He's known as “Wee Davy” or “Davy” for short.
The simple answer is no. 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.
“He's about 25,” Gabaldon said. It's an interesting response. If you're up to date on the series, then you know that Jamie is not dead at the age of 25.
Jamie marries Claire to keep her from falling into the hands of the evil Captain "Black Jack" Randall. They have one child, Faith, who doesn't survive birth; an adopted son named Fergus; and a daughter, Brianna.
She previously told one fan, who hoped for Jamie to time travel in the 10th and final novel: “Sorry, not happening.” Nonetheless, Jamie does have some powers after he was able to project himself into the future and appeared in Inverness with Frank Randall (Tobias Menzies) spotting him.
In November 1774, Jemmy has lice and Jamie shaves the boy's head, revealing an unusual birthmark on his scalp that Claire says would be genetic. Roger shaves his head as well to show that he has a matching birthmark, confirming Jem's parentage.
Rob Cameron, one of Brianna's coworkers, kidnaps Jem, and it appears that he has taken Jem into the past. Roger and William travel through time to find them, but Rob appears at Brianna's home and orders her to tell Jem to disclose the location of the gold.
Roger is the father of Bree's baby in Outlander
The Outlander Season 6 finale included the lice scene. It wasn't quite the same way as the books, but it was still a great way to make it clear that Jemmy and Roger are related by blood. After cutting Jemmy's hair to get rid of the lice, Bree saw a mole.
It's possible that Amelie's sister is the one who gives birth to the line that leads to Claire. Fergus will still be an ancestor but not a direct ancestor and that would mean Laoghaire isn't one of Claire's ancestor.
He may never have called Jamie “Dad,” but Jamie has been the only father figure he's ever known. He's always looked up to Jamie, and this moment shows that Jamie continues to respect Fergus and call him family. There are sadly some who wouldn't view adopted sons and daughters in the same way as biological ones.
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.
During the breakdown of her second marriage, Bree had an affair with Karl Mayer, her divorce lawyer and ex-husband of her friend, Susan Delfino. However, Bree did remarry in the series finale to her lawyer, Trip Weston, making him her third husband.
Claire asks Lord John if he believes she (and Brianna and Roger) are from the future, to which he says that he doesn't, but that he will behave for all appearances as though he does.
They settle in 20th century Lallybroch, following along somewhat with what Claire and Jamie are up to in the 18th century by reading a series of letters from Claire to Jamie.
See, before her wedding, Jocasta signed over ownership of River Run to baby Jemmy so that Duncan Innes wouldn't have any claim to it; Jocasta was the estate's guardian until Jemmy came of age.
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.
When Jemmy holds the stone, it feels incredibly hot. It's so hot, it breaks in his hands. The stone is hot to the touch for Claire, Bree, and Roger, too. It's cold when Ian or Jamie hold it.
Roger is a descendant of Geillis and Dougal's son. Roger has Geillis's green eyes and inherited her ability to pass through the stones.
Apparently, the stones realized that Brianna and Roger weren't ready to leave the 18th century just yet. They both said they'd wished to go "home" as the stones whisked them away, and that's exactly where they went: the place they now consider to be home, back with Jamie and Claire.
It's all pretty bizarre, but Brianna sensibly plays along to save herself, and even convinces Bonnet to let her go home and get Jemmy. Well, at least until Bonnet wants to seal their agreement with a kiss, at which point he realizes Brianna has no real feelings for him.
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. And then Jamie shows up alive and well!
“I curse you. I curse you with knowledge, Jack Randall. I give you the hour of your death. Jonathan Wolverton Randall, Born Sept 3rd, 1705, dies…” she whispers in his ear, and suddenly he knows that she's telling him the truth.
Is it ever mentioned that Jamie knew Frank was a descendant of Black Jack Randall? Yes. Not to spoil it for you but an important story arc that involves Jamie and Randall is built around the fact that Frank is his descendent.
