It is easy to take the answers presented in online databases and add the information to our trees. But, it is important to check the original documents, when they are available.
Recently, I came across a database entry in a marriage collection on Ancestry that listed a marriage date. I used the source citation to get back to the digital image in FamilySearch and checked the information provided.
The date listed in the database was the date the marriage license was filed for, NOT the date the couple was married.
Additional research for the marriage date was needed, but I at least knew the county to target.
