- CA CMBS CMBS Personal Papers:
This fonds consists of photocopied family history and genealogy of the Block and Derksen families. These photocopies are from textual records consisting of diaries, memoirs, records of financial expenditures and genealogical records created or acquired by persons such as Gerhard G. Derksen (1866-1933), his wife Anna Pankratz Derksen (1871-1969), Ella Derksen Block (1909- ) and Isaac H. Block (1905- ). Some of the family history was originally created by Block's ancestors in the nineteenth century. Most of the history was written by Isaac H. Block in retrospect, after 1960. A small part of this fonds is genealogy created by Henry J. Block of Campden, Ontario after 1980.
Block, Isaac H., 1905-1997
