My client wanted me to find interesting stories about her ancestors. Normally, that would have me scouring newspapers and court records, but only after I find the basic information about birth, marriages and death. The civil registration records are not the first place you would think to look for interesting stories, but sometimes they will give you the first hint.
I found the date and place of birth of one of her ancestors in the extract of his birth record in the marriage supplements. A less thorough researcher might have been content with that, but since I know that original records may provide more information and be more accurate than an extract, I consulted a scan of the original birth record.
