[1] The elder Sir Edmund was a slave-owner, who had a number of sugar plantations in Jamaica, British Guiana and St Kitts.
It was rumoured that an anonymous buyer wanted to buy the stones and take them to the United States; if Antrobus had accepted the offer, no-one could have stopped him.
Antrobus was elected as one of two Members for East Surrey in 1841, and won one re-election, then in 1847 both MPs were unseated by Liberal candidates.
At a by-election at Wilton in March 1855, he was elected unopposed as a Peelite, replacing an incumbent from the same party, Charles A'Court, who had stood down to serve as a Special Commissioner in Ireland.
[1] On his death the Baronetcy passed to his eldest son and namesake, Sir Edmund Antrobus, 4th Baronet.
