Merrie is a mermaid from Xanth. Her talent is Siren singing. She was introduced in Fire Sail.
Merrie has bright hair. She has some siren ancestry so she can sing hauntingly, including for bedtime. She was the maid of honor at the wedding of Rhythm and Cyrus. She was the second of eleven girls who were wrong for Lydell.
Human men and women will not have a species in their entries. Also, if the surname of the character is the character's species, it was dropped.
If the character is a child, it will be in the description. The child will more than likely be an adult by this time in the Xanth series.
Many species are single gender, so their entries will not mention it. The species are Fury, Muse, basilisk, cenmaid, cenmare, cockatrice, dryad, maenad, sand witch, sandman, and woodwife. Harpies and nymphs are usually female, and fauns are usually male; but there have been a few exceptions that are noted.
In some instances, I have made educated guesses on gender, species, and some birth years.
