Look for the records of a county in the courthouse that had jurisdiction at the time of the event (the parent county). Because many records were recorded into books, there wouldn't be a way of taking records from just one area of the county over to the new county. There can be some exceptions for finding things in the parent county. Marriage records may have occurred over the county line if one county seat was closer than the parent county seat. So look not in the new or in the parent county, but in the surrounding original counties if you've got someone whose marriage you can't find. (This may even occur in a different state, if you're looking at a county that is a border county.) Karen
