Louis was the youngest of four children. His grandfather Pietrus Trädgård was a
Calvinist refugee from
Bäckebo,
Kalmar, Southern Sweden who arrived at the Cape in 1731 at the age of 19. His grandfather married a daughter of the German Eksteen family. His father was born in
Franschhoek. His family moved to
Uitenhage after his birth, and hence to
Graaff-Reinet. When the English installed Bresler as their
landdrost in Graaff-Reinet, Carel and his two sons settled beyond the
Great Fish River, outside the colony, rather than pledging allegiance with the new government. Carel only returned when Dutch governance was restored in 1803, and died at Bruintjeshoogte, near
Somerset. He farmed at various places in
Graaff-Reinet district before settling in
Uitenhage district in 1810. Later that year he married the 15 year old Martha from that district. He soon moved to Boschberg farm near
Bruintjeshoogte, which was expropriated in 1814. He then acquired De Plaat farm at
Daggaboers Nek, where he was appointed as
field cornet for Smaldeel ward in 1825. He ostensibly had an uneasy relationship with the colonial authorities however, and agreed to rent grazing land from Xhosa chief
Hintsa. In 1829 Louis sent his son
Carolus to graze their cattle along the
Black Kei River, then the northern boundary of
British Kaffraria. In 1833 (or 34) Louis also crossed the neutral zone to join his son. Here a substantial
boer community, at odds with the colonial government, was already living in exile. With Louis acting as their leader, colonel
Harry Smith deemed him an agitator of the
sixth Xhosa war, and planned to arrest him. Tregardt however moved his family and livestock to grazing land between the
Caledon and
Orange Rivers, just outside the colony, where he resided in 1835. ==Northward trek==
