Guest Peggy:
The original version of Utah Carroll (Carl) appeared in Lomax, 1910, without score or chords. (Slightly revised, with score, Lomax and Lomax, 1938) but without chords.
Margaret Larkin (1931) used similar but not identical meter for the tale, and published chords.

I listened to Olie Gilbert # 1, and it seemed to be very close to Larkin.
You can try Larkin's chords and see if they suit you. I have put the chord before the word in the following:

Utah Carroll #2/4 (sung narrative style)

Oh, (G)kind friend you may ask me what (C)makes me sad and (G)still,
And (Bm)why my brow is (Em)dar-kened like (A7)clouds upon a (D7)hill,
Run (G)in your pony closer and (C)I'll tell you the (G)tale,
Of (C)U-tah Carroll my (G)partner, and his (C)last ride on the (G)trail.
