Summarise a Box of Old Birth, Marriage and Death Certificates Into a Family Timeline

Someone has died, or you are just tidying up, and now there is a folder of birth, marriage and death certificates with dates that almost line up and surnames that keep changing. This turns the raw details into one timeline, and tells you honestly where the certificates disagree.
