Here's an entry, apparently for the correct guy, in Ancestry.com, showing he was born in Michigan in 1898. His death date is apparently unknown, however he was married to a lady named (ironically), Marrie, who was born in 1906 in Illinois.
More information, on a Delbridge family geneaology forum, shows that his actual name was Delbert Delbridge, and that they had a son named (confusingly!) Del in 1928, and possibly also a daughter named Hope:
With his orchestra, Del Delbridge was the piano player and leader of the band.
He originally recorded in 1923 as a piano player with Albert E. Short's Tivoli Syncopators, before striking out on his own. You can hear some of their recordings here:
There is a nice photo of the band showing Delbridge, Short, and Wayne King, as well as the other (unidentified) personnel.
The Tivoli Syncopators were a Chicago-based band, and while he was in Chicago, Del took the time to make some rolls for the Columbia Music Roll Company (renamed Capitol in late 1924), some of which were also released on the Supertone label for Sears Roebuck. Here is an (incomplete) list of his piano rolls:

I compiled this list from Mike Montgomery's excellent (although incomplete) rollographies of Columbia/Capitol and Supertone 88-note word rolls, available here:
so that together we can make these rollographies as complete as possible]
Before I leave the subject of his piano rolls entirely, I would like to point out that at least one of them can be heard online via a MIDI file of the scanned roll. If your computer has a normal sound card, just click and enjoy!
