My Unruh and Buller families were on the same Vaderland trip as your Unruhs. How do you suppose they were related? John P[eter] Unruh, b. 1854 and d. as soon as they arrived in Kansas or maybe enroute, married to Helena Nachtegal/Nightengale is my 3rd ggrandfather. I descend through his son Benjamin John, and HIS son John Benjamin. With the exception of John P., these folks are all buried at Karoma Cemetery in Goltry, Alfalfa County, Oklahoma.
