Looking for any info on Rudolph Kilbert, born 1860. Perhaps from Newark, Essex County, NJ. His line of Kilberts is from Alsace Lorraine. He married Sarah in Camden, NJ and they eventually moved to Philadelphia. Rudolph appears in no census information. Sarah begins to show up in 1910. We know nothing about his parents or siblings but can id all of the children he and Sarah had. He is my great grandfather. Thanks for any help or suggestions.
