I am looking for any information available on Adolph Derrer Sr. (My gg grandfather). I know he was born in 1854 in Switzerland and immigrated to the US when he was nine with friends. He married Emma Mordick and had about seven or eight children one of whom was my great grandfather Howard Lyle Derrer who was born in Northwestern Illinois. He died in 1980. He was married to Marie Elvena Willson.If anyone has any info on any of these people but especially about the ancestors of Adolph Sr. I would be gratefull.
