ive read a couple of places that leman russ was orginally a imperial guard commander before being refluffed into the son of the emperor would any one know what book thats in? i know this isnt directly connected to normal deathwatch but im interested in possible incorperating some of it (maybe) into one of my games can anyone help?

I'm not sure, but utnis odd that the imperial gusr'ds main tanknis named after him.

"Couple of places"? I never read about that before tho that does not mean much.

Your best guess would be to ask these places or link them here so we can get some context.

After all your best guess would be to skim thru the old Rogue Trader stuff if you can get your hands on that.
