Virtually nothing is known about Maie FitzGerald. Her only known published work, The Missouri Rag (1900), was printed by A.W. Perry Sons' Music Co. in Sedalia, Missouri that hotbed of ragtime music. The cover of the original sheet music has a portrait of a beautiful Victorian young lady and is presumably the composer herself.
For data housekeeping purposes she is listed in these webpages as a one-off composer.
