Good news for researchers with Missouri black sheep!

Missouri now has arguably the best on-line information about prisoners, including PDFs of the log book including any identifying scars. Two other Midwestern states have transcriptions which may or may not be complete: Illinois and Indiana. (For Indiana, choose "Institution" from the drop-down menu "Record Series," then choose one of several correctional institutions from the drop-down menu "Collections." The resulting search form can be tailored for county and span of years. A null search will not work, so just go through the vowels to develop your own custom list for a given county and period.) Cyndi's List has numerous links but the actual pickings are slim.

So you definitely want your ancestral miscreants to have been caught in the Show-Me State. And while you're there, check out all the other good records Missouri is putting on line. If you state's prison records can better Missouri's, let us know in the comments.
