I originally found Cornelius Luyendyk's death certificate at Kent County Clerk's Office in Grand Rapids, Michigan, but I was excited when Seeking Michigan went live online with the images of death certificates from 1897-1920.
Cornelius Luyendyk is Kirk's great grandfather. The family knew the name of Cornelius, but that was about it. This death certificate gave me a lot of information to research further. I was able to confirm Pieter Luyendyk and Jessie Maasdam as his parents. His birthdate of 15 Feb 1859 is correct, too.
Cornelius Luyendyk was born in Owasco, Cayuga, New York to Pieter Luijendijk and Jaapje Maasdam. He moved to the Grand Rapids, Michigan area in the 1860's. He lived in the Grand Rapids and Gaines Township area of Michigan until his death in 1900.
Cornelius Luyendyk is buried without a headstone in Blaine Cemetery, Gaines Township, Kent, Michigan. He left his wife, Neeltje, who was 22 at the time, with two young children: Peter and Lena.
