Count Olaf's mother and father were killed at an opera performance of La Forza del Destino by Beatrice and Bertrand Baudelaire, with assistance from Kit Snicket, who was in a relationship with Olaf at some point in her life. Olaf survived for some time afterward, until dying on The Island from a harpoon gun wound.
So it seems likely that the Baudelaire parents helped Kit kill Olaf's parents so she could seduce him and steal his money. Make no mistake: Kit is no saint, otherwise Olaf would never have fallen in love with her. She stole something in the Museum of Objects in “All the Wrong Questions”.
Regardless, Olaf would become a killer in the future. It is heavily implied (but never directly stated) that she and her husband were killed by poison dart at an opera performance of La Forza del Destino, thrown by Beatrice and Bertrand Baudelaire, with weapons provided by Kit Snicket. The motive for this is unknown.
While the books imply his parents were murdered, in the TV series, he lost his mother in a fire and his father was later killed by Beatrice, explaining his hatred for the Baudelaire children.
The series is based on Lemony Snicket's books, which were best-sellers when they were released in the early 2000s. As readers will know, the children never confirm who burned down their parents' mansion, although it is strongly suggested that Count Olaf started the fire to claim the Baudelaire fortune.
Violet forced to marry Olaf under duress in his play.
In the first book, Olaf attempts to marry Violet to steal the Baudelaire fortune, doing so by pretending that the marriage is the storyline for his latest play.
In flashbacks, it is shown that Count Olaf was engaged to Kit Snicket, his father was the chief of the city's official fire department, and his mother had died in a fire. His father was accidentally killed one night at the opera by a poison dart thrown by Beatrice Baudelaire that was meant for Esmé Squalor.
Man hands on misery to man, it deepens like a coastal shelf. Get out as early as you can, and don't have any kids yourself." (Hinting that Olaf was a well read person himself at one point before being consumed completely with greed) After quoting the poet, Count Olaf shortly laughs and finally dies.
Beatrice is none other than Beatrice Baudelaire — the dead mother of the Baudelaire children. She died in a fire along with her husband, Bertrand. But before she married Bertrand (and had Violet, Klaus, and Sunny), Beatrice and Lemony Snicket were in love and almost got married themselves.
Stephano. Stephano is Count Olaf's first disguise, used in The Reptile Room, The Reptile Room: Part One, The Reptile Room: Part Two, and Lemony Snicket's A Series of Unfortunate Events. In the book and TV series, he wears a fake grey beard, bald cap, and white lab coat.
Arthur Poe claims that the fire killed both the Baudelaire parents (Bertrand and Beatrice), although no mention has been made that their bodies were ever found, leaving Violet, Klaus, and Sunny to later suspect one of them may be alive.
Regarding the validity and legitimacy of this marriage, it would be voidable until Violet turned 18, because she was not 16 at the time of the marriage. However, it would be legitimized if she and Count Olaf cohabited as husband and wife after she turned 16 (RC 3105.31(A)).
The Baudelaires find out pretty quickly that Count Olaf has only one reason for adopting them: He wants to get his hands on the enormous fortune their parents have left behind. He has so little interest in the children otherwise that he doesn't even give them their own bedrooms.
Type of Villain
Count Olaf is greedy and will go any lengths to get what he wants, even if it involves murder. He appears in every book of the Series of Unfortunate Events, in some form or another. He is also the archenemy of Violet, Klaus and Sunny Baudelaire.
The children remind him that he never asked them to make roast beef, and Olaf becomes angry, lifting Sunny into the air, and striking Klaus across the face after Klaus tells everyone Count Olaf has given them only one bed and a pile of rocks for the three of them to sleep on and to play with.
The union produced a daughter, Wulfhild, who married Ordulf, Duke of Saxony in 1042. Olaf's success was short-lived. In 1026 he lost the Battle of the Helgeå, and in 1029 the Norwegian nobles, seething with discontent, supported the invasion of King Cnut the Great of Denmark.
As he becomes wiser to the world, Olaf begins to fear the negative repercussions that come with change and growing older, lamenting that nothing in life is permanent.
Later, Olaf is recreated during the first chorus of "Let It Go", and unknown to Elsa, comes to life. Two days later, Anna and Kristoff and Sven cross paths with Olaf while traveling through a meadow. Anna's first instinct is to give Olaf the carrot nose that he had been missing.
Esme experienced the most "love" of the three women, Olaf did seem to value her thoughts, opinions and feelings but I don't think he loved her as he was hardly bothered when she quit and broke up with him, she started to be a nuisance to him rather than a partner in crime as well.
In the Netflix adaptation, Olaf also goes in to kiss Violet, although he stops and states "okay" when Violet abruptly refused.
She was the former love interest for both Jerome Squalor and The Bald Man. She was also a former love interest of Count Olaf, although it is unknown whether he became her boyfriend because he loved her, or because she would help him with his schemes.
The consensus amongst the fandom is that Violet and Quigley held hands and/or kissed. Back in the old days a lot of fanfiction writers tried to rearrange this “missing passage” as a writing exercise.
Violet Baudelaire is one of the three Baudelaire orphans. She is the eldest of the three. She is incredibly smart and kind. Violet also has a unique knack for inventing things.
We can assume that Beatrice at one time believed that Snicket was dead. When Lemony was revealed to be alive, she had already married Bertrand and she could not marry him.
