Does anyone know the names of all (or most) of the DG Captains, Chapter masters, etc?
From Flight of the Eisentein:
1st Company - Calas Typhon, "First Captain of the Death Guard, master of the prime company, and right hand of of the primarch"
2nd Company - Ignatius Grulgor "Commander"
4th Company - Ullis Temeter
7th Company - Nathaniel Garro "Battle-captain"
That's four out of the seven total companies.
Calas Typhon isn't from Barbarus by the way. Also, he started out as a Librarian, but when the Dusk Raiders united with Mortarion, the Primarch got rid of the Librarians in his Legion and Typhon started his career to becoming the First Captain of the newly formed Death Guard.
During the Horus Heresy there was also another Death Guard captain named Vioss, not sure which company he belongs to...
Another character from the same story (The Lion) is Charthun, guess he is a lower ranking officer or something...
Also, Typhon is the First Captain is leading Terminators who are collectively known as the Grave Wardens. I don't know if they are like the Justaerin of the Sons of Horus or the entire first company.
