Changes

None of the sources listed give the Sons of Medusa as an Iron Hands successor... So where does this bit come from? Because they've got "Medusa" in their name? If so it's hardly proof enough, or the Blood Ravens would be of mixed Blood Angels/Raven Guard geneseed! Moreover, as can be seen in several artworks depicting Ultramarines, they've been using the gorgon head as one of their symbols too, so they may very well be Ultra successors! /[[User: Nash|Nash]]

I changed the Geneseed and Founding to "Unknown", please give a source for these informations or leave them "unknown"! /[[User: Nash|Nash]]
