Betty, my copy of the 1st Division WWII history has a list of Division KIA. There are three Drakes listed: Julius, Francis, and Benjamin K., Sergeant. Looks very possible that this is the man to whom you refer.
A search of the WWII Memorial registry shows Sgt Benjamin K. Drake, USMC, hometown Elmira, NY, KIA.
This info is included in the National Archives WWII database of NY war dead:
DRAKE, Benjamin K., Sgt., USMCR. Father, Mr. Harry L. Drake, 114 Westmont Ave., Elmira.
I don't know much about researching genealogy, but perhaps someone with the city could help you track down descendants? If so, here is the website for Elmira:http://www.ci.elmira.ny.us/index/index.htmlhttp://www.ci.elmira.ny.us/index/index.html
