River House Hanoverians sadly announces the passing of Elite Hanoverian stallion, Maronjo (Mahon/Marbod), born in 1984.  Maronjo competed through Grand Prix with a learning trainer.  A kind and patient school master to the end, in his retirement he was used as a lunge horse and taught the “feel” of the FEI movements to many mid-level riders. Sound to the end, his final day was spent teaching a lesson and sauntering in the pasture near his beloved mares.

Born and approved in Germany, Maronjo was imported by Otto Fuchs and won his hundred day test in the United States with the then top score of 138+points. Those who saw his cross country performance were amazed, although the factors of character and rideability enhanced his overall score. He was developed to first level by Reggie Lorenz. His jumping ability was noted and when River House acquired him at the 1990 Glenwood Farm auction, several contenders were jumper riders.

Before the advent of frozen semen and the broadening of the imported mare base in the US,  Maronjo bred very large books of mares. He corrected feet, legs and front ends on thoroughbred mares and produced well-grown foals that won at foal shows, breed competitions and AHS mare shows.  Maronjo’s offspring have been very successful in hunter/jumper, dressage and combined training disciplines.  Perhaps they should most be remembered as peoples’ best friends.  River House still receives regular calls from owners loving their Mo offspring, wanting to know more about him and looking for another.

Maronjo will live on through his many offspring – active in multiple disciplines. Maronjo has proven to be a valuable broodmare sire and River House is also thrilled with their crosses between Maronjo and Bretone daughters. The first Maronjo/Bretone cross is now starting under saddle, and we will continue to make more using his frozen semen.

We will miss Maronjo’s kind and quirky nature, but his time was long and fruitful.



Maronjo was an extremely handsome gray Elite Hanoverian stallion by the sire Mahon. Licensed at the Hengstkorung in Germany, he then went on to win his 100-day test with an impressive overall score of 138.06!! His rideability and jumping scores were both over 130 and he received 9s for character, temperament, and willingness to work.

As a Competitor


Maronjo competed in dressage all the way up through Grand Prix. His workable disposition always shined. At 16, our daughter, Emma, showed him fourth-level in the CVDA Fall show, placing 2nd in an open competition. This was her first attempt to show above first level. Maronjo also has champions in hand at breed shows, and his jumping technique would not have prevented a different career path. Maronjo has been ranked as high as 7th on the USEF sire list!! Thanks to his offspring in sport.



On the international scene Maronjo’s pedigree continues to prosper. His sire Mahon now has a dressage index of 140 in Germany, and is regarded as a high producer of dressage horses. His Grand sire, Mahagoni, is the sire of Peron, the highest placed American dressage horse at the 1996 Olympics.

In his mother’s line there is First Gotthard who is out of the full sister to Maronjo’s grandmother. First Gotthard has a jumping index of 140 points in Germany and another full brother is winning at FEI level dressage there.

Offspring by Maronjo

Maronjo Filly

Maronjo  produced many wonderful competition horses that are now making their own marks. Offspring are winners or champions in dressage, eventing and show jumping as well. Foals and mares have been champions at their inspections and breed shows, and have gone on to receive Elite Mare status.
