Particularly with the Census there are many small errors caused by the fact that the census is handwritten. I know of one example where the family name started wit Kn. The census taker, proud of his hand writing, wrote a flowery K followed by the N. When transcribed, the flowery K became TH. THK is an extremely uncommon letter combination. When you compare the flowery K with other TH's on the same page it is obvious that it is different.
Using the comments, I have added the proper transcription, with my documentation. I have done this for several of my ancestors where there is a transcription error, but always with the reason to believe the transcription is wrong
I knew of one person who had to be in the 1810 census from deeds and family records. I looked through ever line on every page in that county, and finally found the person's record attached to the next county. In fact the whole township was attached to the next county.
By adding the correct transcription to this record, the next person who actually tries to document this ancestor may then be able to use the time to finds the document that will correctly find this ancestor's parents.
There are several trees that show parents for this ancestor, some have him being born to his parents when they are both in their 60's, in a time when they were lucky to live into their 60's. There is another having his mother living in England during the period when it is documented that she is having babies about every two years in the Binghamton NY area. I guess they believe a ship under sail made weekly trips between England and New York. probably also believe it was a Cruise Ship.
