Marshua was foaled in 1962 and was an American Thoroughbred racehorse sired by Nashua out of Emardee, by Heliopolis.
The highlight of that season was her victory in the prestigious Selima Stakes at Laurel Park Racecorse in Maryland.
Having led all the way around the 1+1⁄16 mile event, she battled Queen Empress through the stretch to win by a fading neck.
At age three, she placed second in the Acorn Stakes and won the filly classic Coaching Club American Oaks.
She retired with a record of nine wins, six seconds and four thirds in 21 starts with career earnings of $317,599.
