|Note||Our early information for the Clemmer family is taken from Ezra Eby's book, From Pennsylvania to Waterloo, A Biographical History of Waterloo Township, and Other Townships of the County, Vol. 1, Berlin, Ontario, 1895. Eby is our sole source for Valentine Clemmer and his son Abraham Clemmer. Beginning with Abraham's son Henry, we have added materials to support Clemmer family tree information, a major source being a transcription of Martin Mennonite Cemetery of Waterloo by the Waterloo Region Branch of the Ontario Genealogical Society.|
Eby's book has no pagination, but numbers have been assigned to individuals. Valentine Clemmer is shown as number 1916. Eby says that tradition tells of Valentine coming to America and to Philadelphia in 1717 and then to Montgomery County where he is found in 1728. He was said to be a bishop of the Mennonites. The name of his wife is not known but it is believed they had several children. Eby is only aware of Abraham Clemmer and his wife Maria Mosser and Henry Clemmer and his wife Anna Honsberger.
