Hey, Has Anybody Seen My Sweet Trixy Rose?

Junk mail is nothing new -- until today.

I received a flyer from a local piano store for a clearance sale to take place later this month.  I say "I" but that's not quite correct.  The flyer was addressed to "Trixy Rose".  The house number, street name, city, state, and zip code are correct.

Since my parents built the house, no one but they and I have lived here.  My mom's name never was Trixy Rose.  The most my dad ever called her was Honey or Dear.

Unfortunately, I don't think this mystery would interest Sherlock Holmes.
