Shawn,
You did not find "Dow" because the book you found it in made a mistake.
The man's name is actually George Dore of the 126th NY. The flag was
indeed turned in to the US War Dept. and became listed as #63.
Dore rec'd the CMH for his capture. The flag itself is a 3rd bunting ANV
type and is part of the Collections at the MOC in Richmond.
The flag is correctly described in Mr. Rollins' book and is pictured on pg. 34
The link you posted earlier is not for the NY State Museum, but rather a
inventory of the relics on display at the Sanitary Fair held in NY in April 1864.
