Susan Bunstein m. a Kreiger/Creiger in IA or PA

Susan Bunstein married a Kreiger/Creiger in Iowa or PA, she was born abt 1835 in Hecktown, PA, she moved with her parents to Waverly, Iowa around 1850, where they are buried at Harlington Cem. They were Jacob Bonstine & Mary Boorem Bunstein, He was in the war of 1812...I am hoping someone may have some info on Susan Emmaline Bunstein and Mr. Kreiger/Creiger.
Thanks
Tanya
