Sometimes genealogists are tempted to “fix” documents when transcribing them. Don’t. Make comments about the accuracy of the document in your notes accompanying the transcription. Do not indicate the document says something that it does not. Documents can be wrong. But sometimes they are right when we think they are wrong and if we “correct” them, we won’t know what they originally said. This draft card should be transcribed as a birth in Hancock, [State of] Tioga. My notation indicates that the reference is to Tioga, Hancock County, Illinois.  
Guardianship records in some cases may give a precise date of birth, usually stated as the day the child turned a certain age. Not all guardianships give such precise information, but many do at least give an age or an approximate age. These records can be helpful in location where there are not good vital records.
