Roger,
Thanks for sharing this article. Very interesting. That makes six 1865 witnesses accounts which don't mention Stanton saying the "ages" quote (Leale, Tanner, Welles, Taft, Field, Rockwell). Now this new Rockwell journal account is kind of sparse in its details, so if the "ages" qoute was better sourced, I don't think it would change anything.
Regarding the "angels" version of the quote, I think that's been definitively debunked as originating from a 1965 book:
