Can anyone help identify my ancestor? Please and thank you

[mathew]

This is my great great grandfather and I cant seem to find anyone who can help me identify anything about his past. All I know for sure is he went by Black Hawk prior to moving to central ny and then he went by Zachariah Taylor. Anything anyone can do to help would be great, thank you !

If anyone can help maybe identify his attire to see if I am looking in the right place?
