When I was growing up, Robert E. Lee ranked high among America’s heroes. Even Yankees admired him.
I had some distant cousins in Ohio who named their son who was born in 1871 after Robert E. Lee. Although their family was originally from Virginia, they had been in Ohio for decades so I doubt there was any pro-Confederate sentiment involved, just admiration for a great American.
Two of the early generation USN ballistic missile submarines (the “41 for Freedom” boats) were named after Lee and Stonewall Jackson.
