I'm fairly certain that:

a) The 7th key is not a person. They've made most of the map out of the first 5 keys, and confirmed that there are two spots missing. So unless the seven knights made a very irregularly shaped map AND also did not give a physical key to one of them, this seems unlikely.

b) The 'treasure' is not the Holy Grail or the some other artifact pertaining to Jesus Christ. Beyond involving the Crusades, the show does not have very many Christian/Catholic references, and there's no proof that anything that Jesus Christ touched was at Constantinople. It very well could be a weapon, a secret Grimm stash, or straight up treasure (as Constantinople was the trade center of the world at the time).

My guess? It's a weapon, designed to wipe out Wesen. The knights, knowing that the Royal families wanted this to maintain their hold over Wesen, and feeling compassion for the Wesen (as we've seen, many species are not dangerous, and even members of the 'dangerous' species live non-violent lives), hid it. The Black Claw wants it to destroy it--or possibly modify it to target non-Wesen--and the Royals want it because they always have. The Grimms, surprisingly, do not seem to care enough to find it, outside of Nick. Likely, the knights did not tell their families what it was, to prevent them from looking for it and using it. Otherwise, the knights' grandchildren would have, very easily, found the keys and retrieved it together.

Is anyone else extremely surprised that Kessler was actually the family lineage listed in the book? This means that from at least 1790's (but likely back to the 14th century), the Grimms in Nick's family were majority male (keeping the name)... but so far, the majority of Grimms shown were female (Marie, Kelly, Trouble vs Nick and that one old guy who's son was not a Grimm). Of course, the majority of Grimms referenced in the Grimm books are male, but this is very likely attributed to the fact that women were not encouraged to leave home or fight in most societies, and probably would not have been considered as Grimms. Still, it seems pretty weird that they were able to trace Nick's lineage through his mother's maiden name only... and that they didn't bother to trace Trouble's at all. I wish they would take some time to focus on her backstory rather than whatever the hell Juliette is or isn't doing.

tl;dr I disagree with the 'Key is a person' and 'Treasure from Jesus' theories and agree with the 'It's a weapon' theory.
