I don't have a roster, but I have some further information.
The 629th Tank Destroyer Bn. trained at Camp Maxey, Texas, with the 99th Infantry Division prior to leaving for Europe during WW II. I have a couple photos of M-10 Tank Destroyer's from the 629th at Camp Maxey in 1943.
Elements of the 629th TD Bn. were often attached to the 99th Infantry Division during the war, and in particular, to my dad's outfit, the 99th Reconnaissance Troop, 99th Infantry Division, along with elements of other units, to form a task force called Task Force Lueders, named after the commander of the 99th Recon, Cpt. Lueders, and tasked with performing special missions out in front of the advancing allied forces.
