I am not related to this line, but the Illinois State Archives Marriage Index also listed one of my ancestor's names incorrectly on their online site. When I e-mailed them a scan of the actual marriage record, they correct the spelling of the name within 2 days. If you do the same, they will be delighted to quickly make the correction with an explanation that the site was created by volunteer help. You can find the e-mail address to mail the webmaster on the Illinois State Archives site. Debbie McArdle
