John McCausland?

[ErnieMac]

I found this photo on Pinterest this morning (see link). It is titled "Image result for Last Surviving Civil War General". The Confederate flags suggested to me that it was not Adelbert Ames. It looks to me like it is BG John McCausland, but I have not been able to find the image anywhere else online. Your thought and opinions requested.

McCausland it is, the last Confederate general, who died in 1927.

Adelbert Ames dying in 1933, was the last Union general; while Aaron Daggett (d,1938, @101 years) was the last brigadier general by brevet.
