The marriages prior to abt. 1876 will NOT have parents names listed BUT may have an affadavit of age signed by a parent or other adult relative if the bride was under age 18 and or the groom was under age21. Marriages after mid 1870 mostly have parents names listed and might have the location the marriage took place so you can check the church record. I could get zerox copies of all of these marriages for you. Copies are not certified nor are they the best quality but I charge less far less than the will county clerk does. Anyway hope this info helps you. Kathy will county volunteer
