The Galveston Daily News of 4th June 1889 states that by 1840 the firm of Frankland and Jones was established.
It was involved in a number of enterprises such as shipping, meat packing, land and speculation. Among the items shipped were slaves from the Caribbean. Texas was a republic in the 1840s and did not free slaves until 1865.
According to a Charles Frankland descendant in Texas, .Richard ran a plantation known as Chedley Forest in Brazoria County, Texas (approx 30 miles from Galveston); this was the Frankland and Jones base for the slave trade and Richard also hired out slaves to work nearby plantations.

His inventory after his death shows property valued at $196,536, slaves valued at $11,051.00, farm animals and equipment and furniture valued at $1,676.50. He also supposed his sister Eleanor to be dead indicating some lack of communication between the two.
Richard is supposed to have died from yellow fever shortly after making his will ( from Kathy Shajari, Frankland descendant, 2006)
