Hannah's maiden name is Krüger. She's first introduced in "Dark" as Jonas' mother, living and working in Winden in 2019. But in flashbacks to 1986, we see more of the younger Hannah. #dark

Mikkel Nielsen, the son of Urlich and Katharina, goes missing in the first episode of "Dark." It turns out that he time-traveled to 1986, and got stuck there. He's adopted by Ines Kahnwald, and changes his name to Michael. He grew up, married Hannah, and eventually fathered Jonas

Ines Kahnwald is the adopted mother of Mikkel, and Jonas' grandmother. We first meet her in 2019, when she's much older. Throughout the first season, we see Ines working at the Winden hospital in 1986, and as a young girl in 1953.#dark

Daniel Kahnwald is Ines' father, and Jonas' great-grandfather. He first appears in season one, when we see Egon Tiedemann working with Daniel at the Winden police department in 1953. #dark

Katharina's maiden name is Albers, but she's known primarily as Urlich's wife, Katharina Nielsen. She dated Urlich in high school, as we saw in the 1986 flashbacks. Katharina is Mikkel's mother, and also mother to two other teens: Martha and Magnus.#dark

Martha, the only daughter of Urlich and Katharina, goes to high school with Jonas. She and Jonas have had a tumultuous romantic relationship, soured by his realization in the first season that she's technically his aunt. #dark

Magnus is Martha and Mikkel's brother, and the third child of Katharina and Ulrich. We saw him as an adult for brief scenes in season two, though most of his storyline has taken place in 2019 with him as a teenager. #dark

Jana (her maiden name is unknown) is Ulrich's mother. We first saw her as an old woman living in 2019, but also got flashbacks to her life in 1986 when she was grieving her other son, Mads, after he vanished. She was also friends with young Ines Kahnwald in 1953. #dark

Noah is Agnes' brother. He often works as a priest at the St. Christopher's Church in Winden, and travels through time in his middle age, making him appear almost immortal as he pops up in 1953, 1986, and 2019.

Regina is Claudia's daughter. Her father is unknown. We first met Regina in 2019, when she was middle-aged and running a local Winden hotel. In 1986, Regina was a shy and anxious teenager until she met Boris/Aleksander.#dark

Claudia Tiedemann is the primary person, aside from Jonas/Adam, who is leading a faction of people attempting to control time travel. We first met Claudia in her middle age in 1986, and saw how she first befriended Tronte in 1953. As an old woman, Claudia time travels frequently.

Egon is Claudia's father, and Regina's grandfather. He was a police officer in Winden, and oversaw important missing-persons cases in both 1953 and 2019. #dark
