Found my 3rd-great-grandparents, Pieter TON and Maria Van KLINKEN, on Ancestry.com's passenger list (on the ship "E. C. Scranton," which arrived in New York on 7 Dec 1857). Pieter's name was right under Peter TIMMERMAN. The whole list was mis-transcribed. My Pieter is listed as "Peter Con Zimmerman" and so therefore, Maria, his wife is listed as "Maria Zimmerman." Zimmerman, by the way is German for "carpenter," and Timmerman is Dutch for "carpenter."
Also with Pieter and Maria are Adriana "Zimmerman" (Ton) and Cornelia "Zimmerman" (Ton), which I believe are Pieter's sister and perhaps a niece. [Correction: A closer look at the Zeeland Provincial Archives online database led to the discovery that Cornelia was the daughter of Maria Van KLINKEN, prior to her marriage to Pieter TON. It's not clear whether Pieter was Cornelia's father, although she is listed as "Cornelia TON" on the passenger list. I believe Cornelia died young, as she does not appear in the 1870 Federal Census with the rest of the family. In addition, Pieter and Maria named a later daughter Nellie (b. 1860). It was not uncommon for the Dutch to name a child after a deceased older sibling.]
There is also Pieter's sister Suzanna "Susanna" Van KLINKEN, her husband Izak "Isaac" PAPE and their daughter, Netye PAPE. ("Netye" is probably supposed to be Neeltje, who would have been named after Pieter, Suzanna, and Adriana's mother.) They are all with a group from the Netherlands headed for Ohio. My family records show Pieter and Maria lived in Cincinnati for 16 years, then moved north to Grand Rapids, Michigan. I'm not sure what it was about Cincinnati that attracted them...jobs, a Seceder's Church...?
