Role in the Books 
When Ogden explains that Morfin is being summoned to a hearing for having Jinxed a Muggle, Marvolo seems unconcerned; after all, it was only a Muggle, so no harm done. When told that Morfin has broken Wizarding law, he shows Ogden the ancestral ring of the Peverells, and the locket of Salazar Slytherin, as proof he can trace his ancestry back to the earliest and purest Wizarding families. Ogden's protests that blood does not outweigh law fall on deaf ears. Meanwhile, Marvolo is bullying his daughter Merope, becoming enraged when it appears she fancies a Muggle, Tom Riddle, the same one Morfin Jinxed. Marvolo attacks Merope; Ogden defends her, but has to flee Morfin.
When the Ministry return to arrest Morfin, Marvolo resists, and is arrested, tried, and sentenced to six months in Azkaban. When he returns from prison, he finds his daughter has run off with the Muggle; he never again speaks her name, and dies before Morfin gets out of prison.
Marvolo is menacing to strangers, and never wants to associate with others in his area. He is even cruel to his family, particularly his daughter Merope, whom he berates because of her comparatively weak magical talent. He barely even talks to his son Morfin; the thing he values the most, above his children, are the family heirlooms. He is full of immense pride for his heritage as a descendant of Salazar Slytherin, and because of this, holds himself in high regard, even though he and his family are impoverished.
Relationships with Other Characters 
Greater Picture 
The Gaunt family represent the worst aspects of Wizard Pride and pure-blood mania. Although descended from Salazar Slytherin, generations of in-breeding, bigotry, laziness and feelings of superiority have ruined the Slytherin line. Their wealth had been squandered generations ago and the Gaunts now live in isolated squalor, hating everyone who are not pure-blood wizards. Marvolo considers himself a wizarding aristocrat, but in fact is a violent, bad tempered, ignorant tramp. Marvolo is a useless man with no ambitions, no respect for others (including his own children) and no social consciousness.
The folly of both pure-blood pride and "Wizards First" arrogance is a recurring theme throughout the series. The Gaunts and their last descendant, Voldemort, represent the dangers (and foolishness) of racial superiority, intolerance and aristocratic entitlement that is still widespread in the Real World.
