I also looked on Ancestry.com at the Gene Pool.Below is information on this source:
Description: The Gene Pool was created while gathering genealogical data for use in the study of human genetics and disease. Compiling data for genetic research does not require the same type of documentation as traditional genealogical research. The genes themselves verify relationships and qualify or disqualify a person from a particular study. Citing the source of every genealogical fact in the electronic gene pool was deemed unnecessary and cost prohibitive by medical researchers. Millions of individual records were created from birth, marriage and death records; obituaries; probate records; books of remembrance; family histories; genealogies; family group sheets; pedigree charts; and other sources.
The records collected that did not fit a specific study became the project's "by-products" and were schedule to be discarded. After viewing the quality of the source material used to create the gene pool and despite the absence of cited documentation, the electronic rights to the data were purchased, rather than see it destroyed. Extended Description: Thousands of families are known to be present in the database, containing 20 million names in 5 million records. This data covers the entire U.S. for a wide expanse of years. At a minimum, each record contains an individual's name, date and place of birth, and the name of his or her father. A complete record will contain the following information for an individual: Name, Date and Place of Birth, Date and Place Married, Date and Place of Death, Name of Spouse, Name of Father, Name of Mother, Use this database as a finding tool, just as you would any other secondary source. When you find the name of an ancestor listed, confirm the facts in original sources, such as birth, marriage, and death records, church records, census enumerations, and probate records for the place where the even took place.

Here is what the gene pool has on Chauncey Ezekiel Whitford:Born May 2, 1851, Beaver, Crawford, PA; spouse Angeline Amelia Webster; Father Ezekiel Amos Whitford; Mother: Hester Zenota Boyce.
Son - Ezekiel Amos Whitford, b. June 28, 1873, Beaver, Crawford, PA; married Jan 1, 1897 to Ella Law; father Chauncey Ezekiel Whitford; mother Angeliine Amelia Webster;
Son - Penn Perry Whitford, b. Sept. 27, 1871, Beaver, Crawford, PA; married Jan 27, 1890 to Vella Gates.Same parents as above.
I also saw the information submitted to the Ancestry World tree by WBeers.
So it looks like you have your Chauncey census information confused with his son, Ezekiel who married "Ella".
It is also possible Ezekiel is actually named Chauncey after his father and so the confusion since his mother is Hester Boyce.
