If an entry in the AIS Census Index is found to inaccurately reflect the individual as listed in the census records themselves, Ancestry has provided a Feedback Form where members can submit corrections. These will be reviewed and posted periodically to improve the core index. Be aware that due to human error incurred at the time of enumeration and at the compilation of an index, census data may contain misspellings, undercounts, overcounts, false information, missing years and records, and boundary confusions. But be patient, information can be located and your research enhanced even with the problems of census data. Even when people cooperate fully with census takers and tax collectors, as most do, censuses and tax lists are still subject to data errors.
Researchers find misspelled names on almost all census and tax records.
Even when the census taker and census informant spoke the same language, it doesn't mean they understood each other. Spelling, even of names, was inconsistent two hundred years ago. William Shakespeare signed his own name with three different spellings. Cope with this common problem by being flexible. Consider unusual name spellings as candidates for a name that may be missing from the schedule or index.
