Looking for Striegels

I've been gathering information of all sorts of Striegels since 1976, but mainly the descendants of JHB (John Henry Bernard) Striegel. His father Sebastian was born in Schwieghausen, Baden-Wuerttemberg, Germany. He came to the United States with one son (JHB) born in White Sulpher Springs, West Virginia and another in Dearborn county, Indiana. He eventually settled in Baden, Iowa (later transferred to Harper, Iowa, my birthplace). Any info that you can share on Striegels is appreciated. I do have a book on JHB and his family.
