Here is a copy of what I posted as a reply: "There is no database online with that information. The Ancestry database transcribers must have had it as the cemetery name is transcribed by them from the original records/image. For the "U.S. Roster..." on Ancestry, they state: "Original data: United States. Army. Quartermaster General’s Office. Rosters of World War II Dead (all services). Washington, D.C.: U.S. Army".
So either write to Ancestry or the Quartermaster's General's Office for the information you seek.
If you are using the Ancestry database then having the name of the veteran, you also have the name of the cemetery or state the family had body sent. The Ancestry database lists the same names as the ABMC database for overseas U.S. Veterans burials. The online database for burials in the U.S. in our National cemeteries of Veterans is: http://gravelocator.cem.va.gov/j2ee/servlet/NGL_v1http://gravelocator.cem.va.gov/j2ee/servlet/NGL_v1
From what I can see from looking at several different names, transcriptiion name and actual image (on Ancestry's database), the first number is either the overseas cemetery (6401=Margraten cemetery), the National Cemetery, (7523=Jefferson Barracks NC in St. Louis, Missouri) or the state in U.S. the body is buried/sent (6100=the state of Illinois 8500=Texas, 5400=West Virgiana). The state burial would either be in a private, church, county, or city cemetery of the next of kin choosing. Again for what # equals what burial site you would need to contact the U.S. Army directly for that information or start looking through Ancestry's online database and compiling a list yourself as they have both actual image with numbers and the name of the burial site and match them."
Looks like for online research you need the name of the men of the 48th and an Ancestry subscripton so you can look them up on the US Rosters of WWII Dead. The "more information" gives you either the state, National Cemetery, or Overseas Cemetery the remains were sent for burial. When you click on the "actual image" you only get the "number" as I explained in my earlier post. For U.S. Veterans burials all I have ever seen is the State the next of kin had thier loved one sent to, no names of individual church, city, or county cemeteries.The only named cemeteries are US and Overseas Veteran ones. The US Roster does not identifty military units only branch of service and rank. Only the National/Overseas Veteran cemetery Websites seem to have information including military units served.
