A member of House Alde, a noble house situated on the planet of Alderaan, was a Human male who bore the rank of earl. This occurred at some point prior to the Cold War that transpired between the Galactic Republic and the reconstituted Sith Empire. Other nobles didn't think much of the earl, and he was slated to married Gesselle from House Organa when she turned eighteen. However, the wedding was pushed back and eventually called off for reasons that were never made public.
The 2011 Star Wars: The Old Republic video game included a reference to the Alde earl within Gesselle Organa's Codex entry.
