Geillis Duncan
After Claire first time travels to 1743 Scotland, Geillis suspects that Claire is from the future. Geillis is a time traveler from the 1960s originally named Gillian Edgars; she goes through the stones in 1968 to ensure that the Jacobite rebellion of 1745 is successful.

Germain. Claire tried to save them both, but Master Raymond poisoned St. Germain after he confessed to trying to kill Claire.
Claire tells the entire family her true identity of being a time-traveller from the future, but Jenny still views her as a 'witch' or 'faery-woman'. Later in the hen coop Jenny confronts Claire and begs her to cure Ian's illness and prevent him from dying, believing her to have the power to do so.

Yet, even with so many people suspicious of her, there are plenty of characters who know that Claire is a time traveler. As the number of time travelers on Outlander increases, the secret understandably has become harder to keep. But the more people who know, the more Claire and her family could be in danger.
Brianna is the 200-year-old baby
Brianna was conceived in 1746 between Claire and Jamie. Claire then took a trip through the stones and gave birth to the baby in 1948. She is technically 200 years old at the time of her birth, even though she is definitely not a case of Benjamin Button.
How does Master Raymond know Claire is his descendant? His descendants–a few of whom he meets now and then in his travels–have the blue light about them, too; in large degree or small, depending on their talents. So he knows Claire, when he sees her, as one of his great-great, etc. grand-daughters.
