In 1829, Trailor moved to Illinois with his brothers Archibald and Henry. William settled in Warren County, where he was a farmer. In 1841, Henry falsely accused William and Archibald of murdering Archibald Fisher. Logan & Lincoln defended the brothers, who were exonerated for the crime when Fisher appeared alive and well. William died less than a year after the trial.
