I am looking for more information on John Gass, born in Germany, emigrated to the U.S. with his wife Karolina/Caroline (Hirtwick) in the mid-1800s. They settled in Wapakoneta, OH, and had a son named Otto in 1860. John enlisted in the Civil War in October of 1861 into the 37th OVI, Company H. He died two months later on Christmas Day at camp in Clifton, West Virginia.
I am looking for any further information on his military service, as well as any info on his and Caroline's emigration to the States and their lineage in Germany.
After John's death, Caroline remarried to Sebastian Drexler in Wapakoneta, OH, and they went on to have 4 more children: Johanna, Adam, John, & Elizabeth.
