I thought someone would suggest him, so I was going to state that it wasnt him... sorry Eva.
McClellan might have been deliberately obnoxious and voted for Lincoln just out of spite or in error ... we cannot be certain how he voted ... and as you suggested McClellan didnt cark it in 1916 (actually McClellan died in 1885) as my General did. So, not McClellan.
You are though thinking along the correct lines.

When I say "thinking along correct lines", I mean outside of the square ....
"how can we be certain" that this General did not vote for Lincoln? Work that out and I suggest you'll be able to google the answer if you dont know it already.

Close but no cigar. Two out of 3 Roger ... your man died in 1916 and came from Pennsylvania ... just like the person I want.
Unless you are 100% sure that Gregg did not vote for Lincoln in 1864 I'll stay with the name I have.
This person was born in the US. Marquis de Lafayette was not of course and anyway he died in 1834.
