If you're looking for a specific fic like that, you've probably already hit the big three—Archive of Our Own, FanFiction.Net, and maybe even Wattpad if it's older. I spent an afternoon trying to hunt down that exact title a while back. The thing with these 'forgotten brother' plots is they often get written under different names or as part of a larger series, and sometimes they just vanish when an author deletes their account.
I had more luck with AO3's tagging system, searching for 'Harry Potter brother' or 'OC Potter brother' and then sorting by kudos. The filters for 'complete works only' and 'word count > 50k' helped narrow it down to stories with enough substance to actually develop the premise. You might also try adding 'Slytherin Harry' or 'Grey Harry' to the tags, because a lot of those fics feature an older sibling as a guiding figure. Don't sleep on the collections feature, either—sometimes users curate lists for 'Potter Family' AUs.
Another angle is to look for author names you recognize from other big brother-centric fics. If you find one you like, check their bookmarks. Writers often bookmark stories with similar vibes to their own. I found a fantastic, nearly forgotten fic on FFN that way, buried in someone's favorites from 2012. The prose was a bit clunky at the start, but the dynamic between Harry and this invented older brother who was secretly a curse-breaker was surprisingly tense and well-plotted. It's a shame the author never finished it.

Honestly, I can't stand this trope. Most of the time, the 'forgotten older brother' is just a lazy plot device—an overpowered Gary Stu who shows up to solve all the original trio's problems. You know the type: he's usually some super-secret agent trained by the goblins or a prodigy who was adopted by the Founders' portraits. He makes Harry look incompetent, and the whole thing reads like a power fantasy checklist. I remember one fic where this OC brother, Callum, was also a Parselmouth, a Metamorphmagus, and the secret heir to Gryffindor. It got so ridiculous I had to tap out.
But, if we're just cataloging appearances, the 'brother' character is usually an OC named something like 'Charlus' or 'Hadrian,' though sometimes he's a canon character reimagined, like a long-lost son of James from a previous fling. There's almost always a new mentor figure tied to him, too—some ancient, all-knowing being like a goblin elder named Ragnok or a ghostly version of Merlin who only communicates through riddles. The real world-building usually hinges on these new characters forming a separate, 'smarter' faction that bypasses Dumbledore entirely.
I guess the appeal is in the wish-fulfillment of a more competent protector for Harry, but it rarely leads to interesting conflict. The stories become predictable power-ups, not genuine explorations of family or legacy. At this point, I just scroll past any summary with 'older brother' in the title.

Well, a lot of sibling rivalry fics in the fandom fall into obvious tropes—the jealous older brother who bullies Harry, or the resentful one who feels ignored. 'The Forgotten Older Brother' takes a different path that honestly feels more psychologically real to me. The rivalry isn't a constant shouting match; it's a quiet erosion of identity, where the older brother's entire existence is defined in relation to 'the boy who lived.' His magical abilities might be average, his achievements overlooked at Hogwarts, and his parents' worry is always laser-focused on Harry's survival, not his own future.
What I found compelling was how the fic uses magical lore to mirror the emotional dynamic. The brother might stumble upon obscure, foundational magic—ancient runes or creature husbandry—fields considered unglamorous compared to flashy Defense Against the Dark Arts. His mastery there becomes a form of silent rebellion, building a world where he is the authority, not Harry. The rivalry becomes less about direct conflict and more about two siblings operating in completely different spheres of the same magical world, one in the blinding spotlight and the other in the shadowy, deep archives, each nursing a different kind of loneliness.
It doesn't fully villainize either side, which is its strength. Harry is often portrayed as confused and guilty, aware of the disparity but too burdened by his own fate to properly address it. The real antagonist is the external pressure of prophecy and war, which forces their relationship into a distorted shape. The resolution, if the story has one, usually hinges on the older brother's niche knowledge unexpectedly becoming crucial to the war effort, forcing a re-evaluation of what 'power' and 'value' really mean within their family. It’s a slower, more melancholic burn than most fics with this premise.
