becuase my family tree is made up of GEDCOM files from many different sources there is a mixture of content in the “Given Name”, “Family Name” and “Suffix” fields i.e. sometimes the surname is actually in the forename etc.
Is there an easy way to see the various component parts of the overall name so I can visually identify where the wrong data is in the wrong field?
You will want to Edit the way the name is displayed by Adding a new option.
Title / Given / Prefix / RawSurnames / Suffix
This will display all of the common fields (you can add or delete fields) separated by the slash so you see which information is in which field. To further isolate a field if you spell the field in all UPPERCASE the display will do likewise.
An alternative is to set the display to only one field at a time.
