The more I look at the list of qualities associated with the Slug Club the more I think that Harry's parents - and probably some of their friends - must have been part of it.

[Slughorn] also likes the company of the famous, the successful and the powerful. He enjoys the feeling that he influences these people. He has never wanted to occupy the throne himself; he prefers the back seat – more room to spread out, you see. He used to handpick favourites at Hogwarts, sometimes for their ambition or their brains, sometimes for their charm or their talent, and he had an uncanny knack for choosing those who would go on to become outstanding in their various fields. Horace formed a kind of club of his favourites with himself at the centre, making introductions, forging useful contacts between members, and always reaping some kind of benefit in return, whether a free box of his favourite crystallised pineapple or the chance to recommend the next junior member of the Goblin Liaison Office."
(Half-Blood Prince, Chapter 4, Horace Slughorn).

None of these three were stupid. In fact, all of them are described as being extremely bright. If it hadn't have been for the war they would no doubt have had glittering careers before them.

We know that Slughorn was at Hogwarts at the time. Did he recruit James, Lily or Sirius to the Slug Club? Why/why not?

    @Trilarion - I don't think so. It's not a big leap that Slughorn's favourite pupil would be a member of the club but I don't think it's explicitly spelled out

    This is far more upvoted than it deserves to be (says the hypocrite, but still). The canonicity of these images is dubious at best, especially when there's actual primary-canon book evidence to answer the question; and the bit about Malfoy is a) totally speculative and b) irrelevant, since the question doesn't even mention Malfoy.

    @Valorum - Yes, but the movies tend to take a backseat to evidence from the books, owing the the amount of creative liberties the movies took. (I still have nightmares from how they ruined the final battle). Commented Nov 3, 2017 at 16:27

Lily was probably in the Slug Club.

Slughorn says Lily was one of his favorite students, and speaks very kindly of her. He says she was excellent in his class, and presumed Harry had gotten his skills at Potions from her instead of Snape's notes in his textbook.

“Humph. Yes, well. You shouldn’t have favourites as a teacher, of course, but she was one of mine. Your mother,’ Slughorn added, in answer to Harry’s questioning look. ‘Lily Evans. One of the brightest I ever taught. Vivacious, you know. Charming girl.”
Harry Potter and the Half-Blood Prince

The only reason why Lily wouldn't be in the Slug Club is if she chose not to be. That also seems somewhat unlikely, as Slughorn would be unlikely to speak so warmly about someone who rejected his offer unless she did it very carefully so not to make him feel bad.

Whether James would be is less clear.

Slughorn does mention James and remembers teaching him, but doesn't speak nearly as warmly of her as he does of Lily.

James's most noticeable talent was probably Quidditch, since that's what everyone seems to mention about him first. He did seem to consider Quidditch a skill worthy of inclusion; unless he coincidentally chose her for another reason, Gwenog Jones, as the captain of the Holyhead Harpies, was in the Slug Club.

“And at the back – you’ll see her if you just crane your neck – that’s Gwenog Jones, who of course captains the Holyhead Harpies … people are always astonished to hear I’m on first-name terms with the Harpies, and free tickets whenever I want them!”

Sirius is also less clear.

As a member of a pure-blood family, and therefore also likely being thought of as having important connections, Sirius was likely at least considered by Slughorn. Slughorn does refer to him as a talented boy, but there's nothing really indicating he actually joined.

“The whole Black family had been in my house, but Sirius ended up in Gryffindor! Shame – he was a talented boy. I got his brother Regulus when he came along, but I’d have liked the set.”

In addition, Slughorn mentioned Regulus, Sirius's brother, as being a member of his house, but doesn't mention Sirius as being in his club.

It's possible that Slughorn invited Sirius, but Sirius declined, since it doesn't seem like something that he, as a rebel who wanted no part of wizarding high society, would want to take part in.

    This is the best answer and should be accepted. A couple of small suggestions: 1) if James was in the Slug Club, wouldn't Slughorn have mentioned it to Harry? He talked about Lily all the time, and also (as you note) showed Harry his old Slug Club pictures. 2) The final paragraph about Sirius applies equally well to James.

I think the only reason to believe they were not in it, would be personality. We have some definite facts on this subject.

We know that the Slug club existed both before and after they Lily and James were at Hogwarts. Voldemort himself was part of it, very early on, which would be roughly 50-60 years ago from the HBP. We also know that Gwenog Jones (captain of the Holyhead Harpies), was also involved in the Slug Club. Gwenog was born in 1968, while James and Lily were born in 1960.

Gwenog Jones Wikia Entry

So, the question is whether or not James, Sirius and Lily would have been invited. Slughorn says that Lily was one of his "all-time favorite students", and he is courteous enough to overlook her being muggleborn because she was so talented. James, a wealthy descendant of the Peverells (not to mention talented student/quidditch star) would have likely garnered an invitation. Sirius, a Pureblood from an old and rich wizarding family (also a talented student), also was probably on Slughorn's list.

When it comes down to personality it is less clear. Sirius tries as much as possible to distance himself from his family, so he may have distanced himself from Slughorn. Slughorn may have even decided not to have him be part of it, based on his attitude. (Think about Belby, who admits his father doesn't get along well with his famous uncle, and is never seen in the Slug Club again). After seeing that Sirious is unwilling to use his family as a leg up, he may have been passed over for the club, despite his talent. And, based on their friendship, I doubt either would go to Slughorn's parties without the other, they were somewhat of a package.

We know that Lily, gave Slughorn cheeky answers when told she should have been in Slytherin, but I doubt she would have been quite so rude as to decline the occasional party. I am willing to believe that should would have been part of the Slug Club, but there is no proof of that in the books.

And, of course, people like Lupin and Wormtail would have been passed over completely, Lupin has no connections and Wormtail is a useless weenie at best.

    "It can be assumed that Arthur and Molly Weasley are younger that the Marauders..." I don't think we can assume that, they may simply have not had the right connections to get roped into the original OOTP. If anything, I would assume that Arthur and Molly are older, since they already had five or six children (depending on when Ron was born) before James and Lily had their first.

  • @MJ713 - That's possible, I'm just looking at book quotes. Although, it isn't ludicrous to think that even if they were similar in age, that the slug club would have ceased to exist. Commented Nov 3, 2017 at 18:43

Lily was Slughorn's favourite student, and I think it's obvious she was in the Slug Club, too. Even if James and Sirius had received an invitation, I don't think they'd accept it. As a reason for this I could imagine that, like Harry, they did not want to end up in his “collection”. Lupin was good at defending against the dark arts, but I'm pretty sure he wasn't in the Slug Club because he was a werewolf and Slughorn certainly didn't want to have anything to do with such a creature (assuming of course that Slughorn knew about Lupin's illness, but I think he did). And Peter was just untalented and boring. Just my opinion :-)

Lily was definitely in the Slug Club as Slughorn himself said this on many occasions (in the book The Half-Blood Prince) to Harry that she was his favorite student. However in the book there is no mention of James or Sirius ever being in the Slug Club. They surely were talented enough to be in it but as we have seen from book 5 that they were troublemakers like the Weasley twins, maybe that's the reason they never got an invitation from him (not that either one of them would have been interested to be honest). BTW this makes me think, can anyone decline the offer to join Slug Club?

I think Lily and James may have been. But I don't think Sirius would have joined. He would have thought he was too cool to be a part of the Slug Club. Also, he wanted to distance himself as far away from Slytherin as possible. James would have joined because Lily was in it. Anything to be close to the woman you love. Lily was supposedly really good at Charms and would have made it into the club on merit alone.
