John Howlett, Sr.
Place of Birth
Mister Howlett (father, deceased); Elizabeth Howlett (wife, deceased); John Howlett, Jr. (son, allegedly deceased); James Howlett (Wolverine) (step-son); Daken (step-grandson, deceased); Erista (step-grandson); William Downing (Gunhawk) (step-grandson, deceased); Saw Fist (step-grandson, deceased); Cannon Foot (step-grandson, deceased); Shadowstalker (step-granddaughter, deceased); Fire Knives (step-granddaughter, deceased)
John Howlett, Sr. was the son of Mister "Old Man" Howlett. John was known as a wealthy man at the end of the 19th century who got his fortune due to hard work and the inherited fortune of his father. John was eventually married to Elizabeth Hudson. The two had two children together. Their first born was John, Jr. and the second was James (aka future Wolverine). On the Howlett Estate there was also Thomas Logan, the groundskeeper, and his son named "Dog" who became friends with John's youngest son James.

Although John, Sr. was a good man and a loving father, the family life was not as good as could be. One day, John and Elizabeth's first born son, John , Jr., was apparently born a mutant. Due to unknown circumstances, he had died at a young age. It was implied that John, Sr. was the one who killed John, Jr. when the boy attacked his mother and his father couldn't defend her. However, what is known is that the boy scarred his mother's back with his claws prior to his death. John was fairly distraught by being forced to murder John, Jr. In addition, this had a huge impact on Elizabeth, who would not often leave her own room, much less leave the mansion or talk to her other son, James. The lack of a mother-figure in James' life concerned John, Sr. because the boy was already an ill and fragile boy.
One day, Rose O'Hara (a red-headed Irish girl) was brought to the Howlett Estate from town to be a companion to the young James. However, when James' friend, Dog, made unwanted advances towards Rose, James reported this to his father. Much like his father--Thomas (who had a violent short-temper, a mean disposition, and flew into uncontrollable rages)--Dog retaliated by killing James' puppy, Callie. Due to Dog's actions, and failing to control his son, John Howlett, Sr. fired and kicked out both Thomas and his son from their estate.
After this, Thomas, in a drunken stupor and armed with a shotgun, invaded the Howlett Estate with Dog. He demanded money and attempted to take Elizabeth (the woman he had an affair with in the past--who James was the result of). John Howlett Sr. attempted to stop him and defend his family, but Thomas shot him down in cold blood, killing his former employer. At that moment, James had just entered the room and witnessed his father die. When this occurred, for the first time James' mutation manifested itself--claws extended from the backs of his hands. In an uncharacteristic ferocity, James attacked both intruders. The attack left Dog's face scarred with three claw marks, and Thomas Logan was killed when James drove his newly manifested bone claws into Thomas' chest.
Although John, Sr. may not have been James' biological father, he was everything a good father could possibly be, and Wolverine thinks back on him with only good memories ever since he had his memories returned after M-Day.
