I thought I'd share this with anyone who might be looking. I found my great-grandfather, Herman Hauptmann b. 1851, d. 1917. In 1910, he was living in the Pin Oak Township, Madison County, IL and he described himself as a widower. He had married Carrie Prichard (Caroline Wigart was her adopted name) and she died before 1900. He was the father of Louisa, (who married Nicholas Altstadt) William and Henry (who moved to Kansas) and Carl, b. 1894. He emigrated to the US in 1853. According to the census records, he served in the Civil War.
