Hi Sue, have you considered purchasing the marriage and/or death certificates for Edward? The marriage doesn't always have the age, occupation, names of the parents or the place of birth, but can include that information. The information in the death certificate is not always reliable (it depends on the knowledge and reliability of the informant), but often can have details about the person's age, parents, place of birth and length of time in the colony/state. The full details from those two records can assist in locating the correct birth record.
