You asked about 'RAU' and 'ROWE' being the same. Well, "Perhaps" so, as I have found my direct families spelled KUNKEL on Ship records, CONKLE in book stories, and GUNKLE in Baptism church records, and KUNKLE on his head stone. I also have "RAU" that married my 'Orivlle Kunkle', and I have "ROWE" that married myGUNCKIEL lines, and KUNKEL lines, and others. If I can be of more help, share with me your direct line you are working on that connects to KUNKLE, KONKLE, or any other variations, and I would enjoy seeing if I can help. Please give me full names, dates, and locations. It all helps a lot. Contact me direct if you wish - < email@example.com> - I'm in Edgewater, Colorado.
