Lillian Rose Evans + William Sherlock Scott Holmes = Hadrian William Jameson Holmes-Evans.
Lillian is the youngest of two girls, and the first magical in a long line of squibs -- which makes her a Pureblood. She was born on 30 January 1960, and was in the Hogwarts Class of 1976, a Gryffindor.
- Lillian is the only Heiress Slytherin, though she descends from the squib line of the second eldest child of Salazar.
Sherlock is the youngest of two boys, and is a squib from a long line of squibs. He was born on 6 January 1960.
- Even though they have been squibs for centuries, Sherlock is a Pureblood because they only marry other squibs, and they descend from the only line of Ravenclaws. Sherlock is the current Heir Ravenclaw.
Hadrian is an only child, and is technically a Pureblood. He was born 24 July 1980, and was in the Hogwarts class of 1998.
- James Potter, Remus Lupin, Sirius & Regulus Black, and Severus Snape are all Hadrian’s uncles (in sentiment), though Mycroft holds the uncle-by-blood title.
- James Potter/Regulus Black, Sirius Black/Remus Lupin, Single! Severus Snape
- Severus and Regulus are Death Eaters. James, Remus, and Lillian are Neutral/Gray.
Sherlock has to work on Samhain 1981, so Lillian takes Hadrian to James and Regulus’ place. Dumbledore attacks them: James and Lillian die, Regulus goes missing, Severus is pissed off, Sirius is imprisoned, Remus is heartbroken.
After Lillian dies in 1981, Sherlock becomes a single father to Hadrian. Sometime in December 1981, Sherlock is arrested on a false/fake drug charge, and Hadrian is taken from him. Mycroft of course goes looking for Hadrian, but they don’t find him until his 5th birthday. Sherlock and Mycroft go together with some police to retrieve Hadrian from the Dursleys, who have been abusing him on top of having illegal custody of him.
- Sherlock sues the Dursleys, and Mycroft makes sure they serve time. Dudley goes to Marge.
- Hadrian is severely malnourished, so they take him to A&E; John is Hadrian’s pediatrician, and becomes Sherlock’s best friend.
Even though he’s 5, the Ravenclaw genius IQ is easily seen.
Sherlock moves himself and Hadrian back to the Holmes’ ancestral manor so they can both have support, but eventually makes enough money solving cold-cases and helping Mycroft to afford 221B.
- Later, they offer 221C to John.
Severus visits every few months when he isn’t spending time with Draco.
