Rodney, If you have found this same family in 3 censuses in the same county/state, they are probably the same family. I have found age differences as wide as 15 years in 2 consecutive censuses. Samuel was often recorded as Saml which might look like Emil. Keep in mind these factors: 1) Many times the family being recorded was illiterate and depended on the recorder to spell the name according to how he heard it. He may have been guessing himself on how to spell it. 2) These censuses, unless you are looking at original copies, have been transcribed by someone who must decipher a variety of handwritings, many of them horrible, or be working with an almost illegible document. 3) If mom and dad were out in the fields, it might have been another member of the family, even a child, giving the info to the recorder. This might be one reason for the difference in ages. Cheers, Nel
