Kurt Barlow Timeline & Summary

Barlow becomes a vampire, possibly long before the birth of Christ. He may, of course, be exaggerating, as bad guys are wont to do.
Barlow takes the name "Barlow," probably in Austria sometime in the early 20th century.
Barlow corresponds with Hubie Marsten, and they chat about shared hobbies like Satanic rituals and sacrificing children.
Straker goes to 'Salem's Lot to prepare for Barlow's coming. When all is set, Barlow's coffin is placed in the basement of the Marsten House (this is 1975).
Barlow starts wandering around the Lot turning people into vampires at night. Good times.
Straker captures Mark and Susan for Barlow to feed on. Barlow takes Susan, but Mark escapes, wounding Straker. Barlow's hunger is so great he kills his own minion.
Barlow abandons the Marsten basement as unsafe, leaving Susan behind for the vampire hunters to find.
To take revenge on Mark, Barlow kills his parents, the Petries. He also defeats Father Callahan, making the priest drink his blood.
Barlow moves into the boarding house, hiding in the root cellar.
Barlow has his vampires booby-trap the stairs. The trap kills Jimmy, but Mark and Ben manage to find Barlow just as night falls, and they stake him.
Barlow's body disintegrates, leaving behind only his teeth. Gross.
