Building his fortune:
In 1704 while at Vlakkeland Jean buys land to build a house in Tafel vallei.
In 1705 he sells Vlakkeland to his father in law.
Inbetween farming Jean was transporting goods for a fee but now that he's moved
into a small property he's continues on this venture.
He gets land in Cape Town to store his transport equipment, this was located in the current Long/Long market street area.
He sell this property in 1712.
He also sold his house in Tygervallei in 1710.
Grass doesn't grow under is feet as he gets a farm on loan (Langverwacht, north of Tygerberg).
After 13 years of building the farm he request ownership to be granted to him,
and it's granted in 1721.
The farm is back in Le Roux ownership since 1990.
Even though Jean sold Vlakkeland to his father in law,
they had a agreement as both names appeared on the paperwork.
After his father in law's death in 1717, Marie's name appears.
The farm is sold in 1724.
His family moves from Vlakkeland to Langverwacht
but his mother in law moves to Welgevallen, Stellenbosch
(now owned by University of Stellenbosch) which Jean bought in 1723
but put under his son's name.
Restlessness comes to the fore and he sells Langverwacht in 1726.
They move to Welgevallen and continue to farm there till his death.
