Here's bbref.com's page about the 1929 Knoxville Smokies. I've snipped a portion of the roster and will try to determine if I can find more info about these half-named players.
Players are listed with limited info, most noticeably no first name. Digging into the newspapers reveals a bit of info about some of the players.
Brillheart (Sabr ID: 9994f9b9). That would be Walter Brillheart. Now we've got a first name. And we know that he was a right-handed pitcher.
Dietrick (Sabr ID: e9e69bc3). That would be Bill Dietrick. Or as spelling sometimes gets mangled, Bill Deitrick. I think that these two players need to be combined.

Erwin (Sabr ID: 625ec687). That would be "Babe" Erwin. I couldn't find a real first name for him.
|The Knoxville News-Sentinel - June 18, 1929|
Fowlkes. That would be Hi Fowlkes.
Baseball-Reference already has a Hy Fowlkes. Based on other newspaper accounts I would bet that these two players are one in the same. Time for a merge. That would be unnamed Fowlkes (Sabr ID: 8335997c) and Hy Fowlkes (Sabr ID: e43c5e32).
Top center (2), is Hi Fowlkes.

The Fowlkes family has a website featuring Hy Fowlkes, complete with a different photo.
Gore (Sabr ID: 36fe0a97). That would be Joe Gore.

Since this was a test run or exercise, I didn't fully pursue Johnston (or Smith, Stafford [Harold Stafford, probably this Harold Stafford], Tashjian [it is Bert T. Tashjian], or Turner [Glenn Turner, probably this Glenn Turner]).
There's a lot more biographical info to be researched. Dates and places of both birth and death. School and burial info. But this is a start.
