The "Lost" Primarchs
The narratives leave two additional unnamed and undescribed First Founding Legions, Legions II and XI. In some literature the missing Primarchs and their Legions are listed as being "Deleted from Imperial records".[1][2] The only information Games Workshop has ever released that directly addresses them, can be found in False Gods and The Lightning Tower (Dan Abnett).

XI
In the Black Library Horus Heresy novel series, Horus, in a chaos-induced dream sequence, apparently goes back in time and sees the cracked incubation capsule of Primarch XI before the Primarchs are scattered to the warp (the effect this has on the Primarch is inconclusive). Before doing this, he puts his hand on XI's capsule and feels "the untapped glories that might have lain ahead for what grew within, but knowing that they would never come to pass". So this leads us to believe that XI is dead or was never sent out.

II
In the audio book The Lightning Tower by Dan Abnett, Primarch Rogal Dorn while constructing the defenses of the Imperial Palace on Earth in preparation for the coming attack by the Traitor Marines is walking through the palace and comes across a corridor showing statues of all 20 Primarchs. The audio book states that 'an accident befell them that may somehow be a precursor of what happened to Horus'. So my theory is that II survived and founded the Blood Ravens chapter whom we know little of there history.

However
However, Games Workshop has explained the gameplay purpose for these "deleted" Legions: they are available to help those who wish to develop their own, custom Legions. The basic idea is since there were 20 Legions, and half went to Chaos but half stayed loyal, that these two lost Legions would represent the same for "do-it-yourself" forces.
