Cornelis Dykeman (or Dyckman) was baptized on May 12, 1647, at the South Amsterdam Reformed Church in South Amsterdam, Noord-Holland, Netherlands. It was witnessed by his grandmother, Aeltie, the widow of Joris Dyckman, and one "Haertien Dyckman". When Cornelis was four years old, in 1651, he sailed with his parents from Amsterdam. He learned to read and write, which was uncommon in those days among the settlers. He was fifteen years older than his brother, Johannes, who married Jannetje Viele. Cornelis married Jannetje Claessen (or Dircks), born abt. 1656, daughter of Dirk Claessen and Wyntie Roelof. Cornelis is the progenitor of the Connecticut branch of the Dykeman family. They had five sons and four daughters. His family left the Albany area after the Schenectady Massacre of 1690.

Cornelis died in Bloomington (or Bloomingdale), Essex, New York, between the time he wrote his will on September 9, 1711 and the time it was proved, on March 3, 1712. He is the "ancestor of the Bloomingdale branch" of the Dykeman family. Bloomingdale is a hamlet in the town of St. Armand, Essex County, New York. It was incorporated as a village in 1852.
