Sarah Rogers was the daughter of Steve Rogers, Captain America, and the X-Man
James Rogers was the son of Captain America and Black Widow. After James was born, he and the rest of his adopted siblings were secretly hidden within an Arctic base to be safely raised by Tony Stark.
Sharon Carter and Steve Rogers have a daughter named Sharon Rogers. Created as part of Captain America's 75th anniversary, she is from an alternate timeline where she now serves as Captain America.
Is Sharon Carter Captain America's daughter? No. Sharon Carter was originally Peggy Carter's younger sister. Because time marches on, but comic characters do not age, she's now Peggy Carter's grand-niece.
In the final minutes of that movie, Steve Rogers travels back in time to find young Peggy and live out the rest of his life with her. We know from Captain America: The Winter Soldier that Peggy got married and had two kids, and Endgame seems to confirm that her unseen husband was actually Steve Rogers post-time travel.
So, while alternate timelines exist, the whole point from what I understand (and as explained by the writers) is that Steve marrying Peggy is always what happened. By returning the stones to their proper place, he preserved the timestream as Banner promised the Ancient One they would.
In the comics she seems to have never married, so there isn't even any canon from there to draw upon. Actually, in the Ultimate universe, she married Bucky Barnes, who survived World War 2 and aged naturally alongside her. Obviously, this cannot be true in the Cinematic universe.
The kiss beat off classic smooches from films including Lady and the Tramp, Titanic, and Casablanca. The kiss between Steve Rogers (Chris Evans) and Peggy Carter (Hayley Atwell) at the end of Avengers: Endgame has been voted the best movie kiss of all time by RadioTimes.com readers.
He DIDN'T kiss his granddaughter. That would make Sharon Carter Peggy's granddaughter as well, which she is not. Sharon is Peggy's great-niece, meaning that, in the timeline where Cap marries Peggy, Sharon is his great-niece as well.
Being Peggy's niece naturally placed Sharon in Steve's orbit as a potential love interest, and she proved to be a very helpful ally to Steve during the events of Civil War. It was during Sharon's final scene with Steve that he kissed her as a way of thanking her for the support she provided.
UnrevealedRed Skull
Red Skull dropped Captain America out of a helicopter but not before telling him that he was Cap's son. Captain America and Gail Richards had relations right before he went off to fight in the war, and Gail became pregnant.
Black Widow's first romantic relationship was with a soldier named Nikolai, who she met while both were serving with the Russian Army during WWII. There was no backstory for the young soldier, but Natasha and Nikolai fell in love and were eventually married.
Captain America
The two of them became very close friends over the years. They usually never go on a romantic level, but Natasha does understand Steve on a level. When they were undercover, she told Steve to kiss her, but it didn't really mean anything, as they just see themselves as siblings.
Marcus manipulated Carol's emotions subliminally like his father did before him, and made her love him. He impregnated Carol with literally his own seed, then sent her back to the moment she left with no memory of her time in Limbo.
In The Avengers #200 (Oct. 1980), which was written by Bob Layton, David Michelinie, George Pérez, and Jim Shooter, Ms. Marvel is kidnapped by a character named Marcus (the apparent son of Avengers foe Immortus) and taken to an alternate dimension, where she is raped by Marcus and impregnated.
'Avengers: Endgame' writers confirm Captain America has always had two children.
We know that Gamora wasn't at Tony Stark's funeral - unsurprising considering that she didn't know him, really - so she must have fled after the battle was won.
Carol Danvers, aka Captain Marvel, never got married to anyone in the Marvel Cinematic Universe. The closest relationship she has had was with Monica's mother Maria Rambeau in the first Captain Marvel film. But currently, there are many rumors floating about Captain Marvel being married.
Taking the codename Agent 13 in her aunt's honor, Sharon teamed with Cap on several S.H.I.E.L.D. missions and they fell in love, partly because of the woman's remarkable resemblance to a younger Peggy, though the hero was unaware the two were related.
However, the how and when it happened ultimately hurts Steve and Peggy's MCU romance. Captain America losing his virginity to a USO girl in 1943 means that he did so while very clearly having strong feelings for Peggy. They had yet to act on them at this point, but their interest in one another was quite obvious.
Peggy Carter first appears in Captain America: The First Avenger, which is set in the early 1940s during World War II. Working for the military, she falls in love with Steve Rogers, who has recently become Captain America.
love interest of Captain America in flashback sequences. She would later be better known as a relative of Captain America's modern-day on and off love interest, Sharon Carter.
In Black Widow (2010) Issue #10, Natasha and Bucky go out on a date and she tells him she loves him. In Winter Soldier (2012) Bucky says that he was a soldier with no home, until Natasha gave him one. Natasha calls Bucky “Darling” and “Sweetheart” and other pet names in Russian/English.
In Avengers: Endgame, Pepper Potts is reunited with Stark. Over the course of the following five years, they go on to get married, have a daughter named Morgan, and live at a lakeside cabin until Stark is recruited by the Avengers to undo the Blip.
Bucky Barnes was a childhood friend of Steve Rogers (aka Captain America) who accompanied him on his missions during World War II as an Army press photographer. Surviving the war and believing Rogers had died during his last mission, Bucky eventually married Rogers' fiance Gail and had a huge extended family.
