There are 2 ways of looking at umbrella titles from a researcher's point. They can get in the way of accuracy if misused as seems to be the case with 'The Unfortunate Rake'. However, in everyday discussion
it would be impractical if not impossible to keep referring to Child 295B or Laws P27a or Roud 27798 or ODNR 364, so to counter this I use my own Master Title index alongside these 4 systems. This is based upon the most frequently used published title. When I'm studying a particular ballad and comparing all of the versions, if a particular version comes without the singer's title and only gives an umbrella title I leave it blank to avoid inaccuracy.
