John Bloomfield, 2nd Baron Bloomfield
From 1824, Bloomfield was attaché at Lisbon and was transferred as secretary of legation to Stuttgart in the following year. He was sent to Stockholm in 1826 and came as secretary of embassy to St Petersburg in 1839. Five years later, he was promoted to envoy. In 1846, he succeeded his father as baron and in 1848, he was awarded a Companion of the Order of the Bath (CB).
Bloomfield was appointed ambassador to Berlin in 1851 and on this occasion was advanced to a Knight Commander (KCB). In 1858, he was further honoured as a Knight Grand Cross (GCB). He reached his highest post as ambassador to Vienna in 1860 and was sworn of the Privy Council. On his retirement in 1871, he was created Baron Bloomfield, this time in the Peerage of the United Kingdom, which enabled him to a seat in the House of Lords. He represented County Tipperary as a Deputy Lieutenant.
Marriage and family
On 4 September 1845, Bloomfield had married Hon. Georgiana Liddell, the 16th and youngest child of Thomas Liddell, 1st Baron Ravensworth and a former maid of honour to Queen Victoria.. The couple had no children. Lord Bloomfield had an extramarital daughter named Thecla born in 1833 by Swedish actress Emilie Högquist, and a son Albert whose birthdate is unknown. Albert was not mentioned after Emilie Högquist came under the protection of King Oscar I of Sweden. 
John Arthur Douglas, Lord Bloomfield died without legitimate heir in 1879 at his home, Ciamhaltha, near Newport, County Tipperary and his titles became extinct . Bloomfield was buried in his family's vault at Borrisnafarney parish Church, beside the Loughton Demense and Moneygall, in County Offaly. An impressive memorial exists in the church in his memory.
"The interior name plaques, that commemorate those who lie there, ensure that history will not forget them: they read 'Thomas Ryder Pepper 1828; Mrs Bloomfield 1828; Mrs Ryder Pepper 1841; Lieutenant General Benjamin Baron Bloomfield 1846;"
