If we go off the premise they would have been completely unaware of who they are, until a certain time, then we have to assume that would be like dropping a bomb in somebody's lap, to give it to them all at once.
You could prepare a person like that for their role ahead of time by exposing them to certain things, without exposing to them who they are.
That would be an easier way to do it, so as not to fry the person's mind completely when the time came, what they would be exposed to is a matter of hashing out logical inferences through conversation.
Who they are, in relation to genealogy/lineage, would only be somebody who's family had been involved in the usual shadowy " secret society " groups everybody loves to talk about, likely compartmentalized like secret societies are known to do, and I would think, completely unknown to the person until a certain time or event.
I say that because if they knew, or had known, the cat would have been out of the bag long ago, at least to them.
So then there's what the person would have been exposed to, that would relate to the above topics, but wouldn't have been enough to tip them off to who they really were supposed to end up being.
Could have been an introduction to GLP, for example, where all the information would be, hidden in plain sight, and only recognizable to that one person.
In any case, I think there were events that would have happened for this individual, that would have been part of a preparation, but not a revealing, and then there would have been an event/series of events that would start to reveal to this person who he was, which would probably be the more difficult part of the process.
There could be habits and attachments somebody somewhere could be waiting for him to drop, maybe he's a couch-potato like Michael said.
I think we can safely infer some things, like how the process would happen, by logic, and then some things, like how long, when, where, etc, would be debatable at best until an identity is narrowed down, and the story is accepted by the peanut gallery, which he's probably sitting in.
MkUltra . The persons every move being watched. Notice how I say person because everyone is reffering a nobody to "him"
