As the final pages of volume 34 come in, Attack on Titan shows Mikasa living life as a wife and mother. She is shown sitting at Eren's grave with a man facing away from readers. It seems the guy is none other than Jean, and the couple has a small child between them.
Now, as for the manga, we know that Mikasa ends up marrying and having a child, eventually dying of old age. One scene shows her family, her daughter and what we assume is her husband, in front of Eren's grave.
"Mikasa adopted the child so he can inherit the tattoo" Adoption was never mentioned and what's the point of giving a child the azumabito symbol if they're not a part of the azumabito family?
In the end, she is alone by Eren's grave, remembering their childhood while waiting for Armin, Jean, and the others. Thus, if we go by confirmed information, Mikasa doesn't marry anyone.
Short answer: Yes, Mikasa married Jean.
In the popular parody series A Slap on Titan by Tom Andre, Armin falls in love with Annie and describes himself as the 'Crimson King' and Annie as his 'Dark Queen'.
No, Eren won't have a child with Mikasa. Mikasa won't have a child period. At least not by the end of the series. After the credits roll, it becomes pointless to discuss what's going to happen in her life.
Christa is the wife of Eren.
Mikasa's mother (ミカサの母 Mikasa no haha?) was the mother of Mikasa Ackerman and wife of Ackerman. She and her family lived in a forest near Shiganshina District.
If there's one thing clear about Attack on Titan's Mikasa Ackerman, it is that she is devoted beyond all reason or logic to Eren Yaeger. For most of the story, it seems like her loyalty arises from the time he saved her when she was kidnapped as a child, but the latest plot developments imply some other force at play.
10 Eren Protected Her From Her Kidnappers, Killing Two Of Them. Eren proved his love for Mikasa before the two of them really knew each other.
Several other characters refer to Eren as Mikasa's boyfriend, and though she protests, she usually blushes at this suggestion. When Mikasa thinks Eren is dead, she nearly commits suicide by throwing herself at a Titan. When Eren is inside a Titan, Armin can't bring him back to reality until Eren remembers Mikasa.
Mikasa Origin and Meaning
The name Mikasa is girl's name meaning "three bamboo hats".
Mikasa is part of the aforementioned Ackerman and Asian clan, therefore, she cannot turn into Titan.
Louise (ルイーゼ Ruīze?) is a member of the Jaegerists. When she was younger, Louise and her mother were attempting to flee Trost District during a Titan invasion, where she was saved by Mikasa Ackermann.
In the Attack on Titan Junior High series, it's heavily hinted that Annie has a crush on Eren, who's very oblivious towards it.
MIKASA AND LEVI ARE SECOND COUSINS.

Alternate Universe — Eren sends Mikasa a vision where Mikasa truly were to confess her feelings to Eren, the two then run away to live together as a couple for the remaining of Eren's final years.
Eren Yeager and Mikasa Ackerman are two of the main characters in Attack on Titan. The two have been together since the very first episode of the series.
Eren sees Mikasa as an annoying mother figure who only protects him cos she thinks he's a kid who needs protecting. 2. Eren learns the real reason Mikasa protects him is because she just wants to be with him.
In this version, Eren and Historia do have a romantic relationship and he becomes the father of her child.
When it comes to Attack on Titan's main trio, most fans have come to the conclusion that Armin and Mikasa are simply platonic best friends. These two always have each other's backs, but there's never been a scene or bit of dialogue to suggest that either of them is interested in anything beyond friendship.
While there are not many canon romantic relationshipsin Attack on Titan, the few that exist are only signified in minor gestures. The friendships formed are at the forefront of nearly all the decision-making fans see from the characters (aside from survival, of course).
