The 143 Ohio Inf. was put into service in early 1864 for 100 days, in Columbiana County, Ohio. At the time, the Amon Boys who joined were 32 and 34 years old. Joseph would have been 30 years old and his four brother was born in Columbiana County Ohio in 1832. The family lived there. Like I siad, after the two brothers joined the 143rd Ohio, there is no other info on Joseph Amon. When did he die and how old would he have been if born in 1832?
