  Quotations
  Captain Samuel Shannon is frequently mentioned in the public records, and he had something more than a local reputation. He must have been very popular, as the name "Shannon" as a Christian name is so common throughout the valley as to be noticeable.

  Everything in my life is okay except I have this terrible problem with my sister Shannon. I'm spelling her name the way most people would. She spells it Sionna ever since the priest told us that's the real Irish way to spell it. It's the name of a river and a goddess. Shanny doesn't think she's a river. She's really Shannon Marie.
