By the time my family hit Cass County, Nebraska the surname was spelled Heil. But in Tazewell County, Illinois....on the marriage record, it was spelled Hyle. Adam Hyle who married Anna Marie Lautenschlager in 1852 had been born in Darmstadt, Hessen in 1814. This was his second marriage as wife number one, Schafer, had died in 1851. This man went by the name Adam but his full name was Johann Adam Heil/Hyle. One family story says he had a brother named William. Adam's sons were named Wendell, William, Heinrich and George. Any help appreciated.....Penny
