This is from 1805: Austerlitz by Robert Goetz:
Infantry of the Imperial Guard
1st Bde (Grenadiers a Pied) – GdB Pierre Auguste Hulin (Hulin was absent, commanding in Vienna, so I assume – but don’t know for sure – that command fell to Colonel-Major Jean Marie Pierre Francois Lepaige Dorsenne)
2nd Bde (Chasseurs a Pied) – GdB Jerome Soules
3rd Bde (Italian Guard) – GdB Teodoro Lecchi
Cavalry of the Imperial Guard
Gendarmerie d’Elite – detached to Brunn
1st Bde (Grenadiers a Cheval) GdB Michel Ordener
2nd Bde (Chasseurs a Cheval) Colonel-en-Second Francois Louis Morland
Artillery of the Imperial Guard
Commander Francois-Henri-Eugene Daugier
According to Hourtoulle (Austerlitz: The Empire at its Zenith) the Chief of Staff of the Guard was Roussel and Bessieres’s ADCs were Cesar de Laville de Villa-Stellone, Lebrun, D’oullembourg, Louis de Seganville, Leinsteinschneider, Desmichels, Lapeyriere and Barbanegre.
I hope that is some help.
