E.D.,
I think I found them!! 1860 Census for Perry County MO (outside of St. Louis, where they both enlisted.) There is a Herman Jungclas, age 27 and a Cassey Jungclas, age 23. Their enlistments show ages of 28 and 25, respectively. This lines up pretty well and could just have the variance based on birth months vs. census/enlistment dates. They had a son Frederick who was 11mos as of the census date, who was born in Missouri. Both Herman and Cassey (Charles??) show they were born in Hanover(?). Herman was shown as a laborer. I will do some more digging when I get the chance. Kerry
