I have ancestors that have fought in the Revolutionary War, the War of 1812, the Civil War, and on up to the present
.
I too have ancestors who fought in the RV, 1812, CW,WWI, WWII and Vietnam. (The last one we were in). One served during Korea and was on orders when the Cease Fire went into effect.
You never know wher you search will take you. I researched my great great grandfather's last battle at Murfeesboro, Tenn. i wrote it up and found that a buddy of mine looked at it and his great great grandfather was at the same place and same time. (we knew by the regiment they were in) His ancestor wore Grey, mine Blue.
I love history
