Anna's year of death is listed as 1909 in "Genealogies of Three Large Families of Lewis County, New York: The Farney Family 1795-1988; The Rev. Rudolph Virkler Family 1792-1988; The Zehr Family 1789-1988 1989" (third update, Two Volumes, 1997 pages) vice the 1919 date cited elsewhere. The same date is listed in the first edition published in 1933 and the second edition published in 1969. These are admittedly secondary sources. Is there a Zehr family primary source, or a competing secondary source?
