Always make certain you have the dates correct.
An attendee at a computer workshop wanted me to help them locate an ancestor in the 1880 census. They gave me her name, date of birth, and family information in an attempt to help locate her. We spent about 10 unsuccessful minutes when I asked him if he had any other information. The gentleman told me he had the ancestor's obituary. Reading it, I knew why we had not found her in the 1880 census. The ancestor had died in 1873.
Make certain the date span of the record fits your ancestor's lifespan or chronology. Otherwise you may be wasting your time.
