How could it be that there are children of civil war veterans?

Lets guess that these are 90 year old now... so born in 1932.
Assume their mothers were young (20 year old), but got married to someone with a guaranteed income (ie a government pension).
Assume their fathers were 80 when they were born (1932 minus 80 is 1852 as the fathers birth year).
In the last year of the civil war (1865) they would have been 13 years old. Possible as a drummer or even as a late-war conscript for the south.

“Lets guess that these are 90 year old now... so born in 1932”.

That would make them 80.

Do a math check. I don't spell check people but I do math check.
