Salute to your family members, Beulah and Andrew! My Georgia great-grandfather and his 2 younger brothers served in the same unit (Co H, 11th GA)...he lost one to consumption, the other at Second Manassas. Many other connections died of wounds or disease. I have yet to be able to collect stats on most of my Union ancestors, besides my 2x gg who did time at Libby Prison.
Reading Bruce Catton recently, I sympathized with the poor soldiers wounded at Spotsylvania, being painfully evacuated to the field hospital at Fredericksburg and probably wishing they'd died on the battlefield :(
