|“||Just leave it to me. I can talk a dog off a meat wagon.||„|
|“||A cocky young Irish thief and stick‐up man who comes from a long line of criminals and political dissidents. He always wants a piece of the action and believes in himself...perhaps a little too much.||„|
|—Description by Rockstar Games.|
Sean was born in Ireland (presumably Donegal) and spent his early childhood there. Sean's father was Darragh MacGuire, an infamous Fenian outlaw who fled to America with Sean, before being hunted down and killed. The young Sean was sent to a reform school, but it did little for him.
Sean first met Dutch and Hosea at a bar somewhere in North Elizabeth. After seeing a fancy pocket watch that Dutch had, Sean followed the pair into the dark alleyway and threatened them at gunpoint. Much to Sean's surprise, both Dutch and Hosea simply laughed and dared Sean to shoot them, which he did. It turned out that the pair had spotted Sean first and silently taken the bullets out of Sean's gun. Instead of killing him, Dutch and Hosea decided to give Sean some food and inducted him into the Van der Linde gang.

Horseshoe Overlook Chapter
After the botched ferry robbery in Blackwater, Sean became separated from the others and was one of the few members who did not end up with the gang in their new hideout at Colter. He was subsequently captured by bounty hunters led by Ike Skelding and interrogated for information on the gang, but Sean told them nothing.
After moving to Horseshoe Overlook, a new hideout close to the town of Valentine, the gang hears from Josiah Trelawny about Sean's aforementioned apprehension by bounty hunters. As a result, Arthur, Javier, Charles, and Trelawny set out to rescue him. They meet on a hilltop overlooking Blackwater, where they discuss their options, deciding to rescue him before he reaches a Federal Prison that he was being transferred to. After spotting Sean being escorted off of a boat, Trelawny decides to distract some bounty hunters, allowing Arthur and Javier to silently neutralize them. Soon afterward, a large gunfight ensues, resulting in the gang finding Sean hanging upside-down from a tree at a camp. After being freed, Sean thanks his rescuers and accompanies them back to camp.
After his rescue, a celebration party is thrown for Sean at camp. Along with the rest of the gang, Sean gets exceedingly drunk. As the night wears on, he begins flirting with Karen Jones, and the two ultimately retire to John Marston's tent to have sex.
Sean later decides to join Arthur, Charles, and John on a train robbery, despite not being invited. He is sent to loot the baggage car during the operation, and is almost killed in a tussle with guards further up the train, but is saved by Arthur. After the law descends on the scene, Sean successfully escapes with the others.
Clemens Point Chapter
|“||He was like an annoying little brother to me... what fun we had riding together.||„|
|—Arthur lamenting Sean's demise, if the former's Honor is high.|
Sean joins Arthur and Hosea Matthews in working for Catherine Braithwaite, who asks them to burn the tobacco fields and products owned by the rival Gray family. Sean talks his way into Caliga Hall with Arthur in the back of the wagon, after which they hide their wagon and eliminate a Gray security guard accompanying them. While Arthur pours the moonshine over the tobacco fields, Sean takes care of the sheds and buildings; when this is done, the duo ignites everything with fire bottles. After fighting off the Grays, the two find payroll from another wagon and flee the area.
Sean is later present alongside Bill Williamson and Micah Bell in the town of Rhodes, joining the two and Arthur on a potential “job” providing security for the Gray family. However, as the four are walking through the street, they are ambushed by the Grays' hired guns, and Sean is immediately killed by a shot to the head from a sniper.
After clearing the area and killing Sheriff Gray, a furious Arthur blames Sean's death on Bill and Micah's carelessness. Arthur expresses his affection for Sean and asks Bill to give him a proper burial. Sean's death also affects Karen, who becomes an embittered alcoholic.
MacGuire is said to be a cheerful man who enjoys spending his time telling stories at the gang's campfires, particularly about his family history. He loves being a part of the action, but he is relatively inexperienced and often overestimates his own abilities. At Clemens Point, he playfully tries to poke fun at Arthur, calling him 'English' and 'King Arthur'.
Sean appears to have a positive relationship with Lenny, who once tried to teach Sean (who is illiterate) how to read. The two are often seen conversing, and Lenny tells Arthur at one point that he likes Sean. By contrast, Sean often expresses his dislike of Micah.
Sean has a generic, very much stereotypical Irish accent. Unlike Molly O'Shea, who has a distinct Dublin accent, MacGuire's is harder to pinpoint. The actor, Michael Mellamphy, is a Cork native but MacGuire has no distinct Cork accent.
Sean has shoulder-length ginger hair, green eyes and is slightly unshaven. He usually wears a jacket of a light bluish-grey color over a dirty white union suit and a red and brown patterned vest, accompanied by blue jeans and a green bowler hat. Unlike most members, this is the only clothing he wears, with only slight variations.
When Sean is rescued from Ike Skelding's Boys, he is shown wearing black jeans held up with suspenders, along with a grey shirt buttoned at the top with a black square shape on the front going from the shoulders to the chest, as well as black cuffs.
