His son, of the same name, died in Calcutta 23 December 1829 aged 29. He had been judge of Jessore, India.
In an LBS blog, Chris Jeppesen notes that the younger John Rycroft Best "obtained a Writership [East India Company civil-servant] in 1818 through the patronage of EIC director James Daniel, a friend of his father since school, whose family were renowned Bristol merchants and held the mortgages on several of Best’s plantations. Although John Rycroft jnr died eleven years later, in turn, his two sons entered the EIC in the 1840s. By the mid-nineteenth century memorials had been erected in Barbados and India commemorating the family’s presence across the empire."
