Ganyesa is the main town of the Barolong boo Mariba, a faction of the Barolong that split from the Kuruman community in about 1765 under Kgosi-Kgolo Mochware and lived as pastoralists and hunters. In the late 19th century, competition with Kora traders for the Kalahari trade led to friction between the communities. After the British established the British Bechuanaland colony in 1886, Ganyesa was designated as a native reserve, with an area that in the late 1950s was estimated at 12,858 square miles (33,300 km2). It was later that Kgosi-Kgolo Mochware made the strongest form of Barolong boo Mariba and His descendants were:

1.Makgobi
2.Gaetsalwe
3.Pheko
4.Selepile
5.Borupile

Kgolo Mochware reigned for a period of time and later on his descendants of his other branch took over who is Kgosi Kgotlakoma Mochware and made a significant role in the administration of Barolong boo Mariba Boo “Ganyesa”
