Deadpool & Wolverine
Logan's life began in Cold Lake, Alberta, Canada, sometime between 1882 and 1885. The mutant who would come to be known simply as "Logan" was born James Howlett, the illegitimate son of Elizabeth Howlett (who was married to John Howlett, owner of a large estate) and the Howletts' groundskeeper, Thomas Logan. As a boy, James was notably frail and prone to bouts of allergic attacks. He was largely neglected by his mother, who had been institutionalized for a time following the death of her first son, John Jr.
James spent most of his early years on the Howlett Estate grounds with two playmates that lived at the estate with him: Rose O'Hara, a red-headed Irish girl who was brought in from town to be a companion to young James, and a boy nicknamed "Dog", Thomas Logan's son (and James's half-brother). The children were close friends, but, as they reached adolescence, the abuse inflicted upon Dog warped his mind. Dog made unwanted advances towards Rose, which James reported to his father. In retaliation, Dog killed James' puppy, leading to the expulsion of Thomas and Dog from the estate.
