Hi! My daughter and I are doing genealogy work and have not been able to come up with information prior to William Boltz, born October 1, 1883, at Denhof, Russia: married to Elizabeth Hettinger February 14, 1906, in Denhof, Russia; and died October 21, 1968, at Windsor, Colorado. They were Germans living in Russia and immigrated to the United States on the Lithuania Steamship in February of 1910. His passport lists him as Johann-Wilhelm Boltz. We are looking for his parents names, births, marriage dates and deaths. Would you have any information or hints as to how to obtain this data.
