Note:
(a) "But just 100 years after his death [in 1911], he has been all but forgotten about in his home town in County Armagh. A new project launched with a £10,000 grant from the National Lottery [of UK] via the Heritage Lottery Fund hopes to change that.
Craigavon Historical Society has begun working with children at Sir Robert Hart Memorial Primary School in Portadown."
(i) The English and north German surname Hart means stag, from Middle English hert (for stag). See Hertfordshire https://en.wikipedia.org/wiki/Hertfordshire
(Greater London to the south; its county town "Hertford * * * derives its name from a hart (stag) and a ford, used as the components of the county's coat of arms and flag [both of which are displayed in this Wiki page]")
Craig can be a surname or given name, both of which are "derived from the Scottish Gaelic [noun] creag" [en.wikipedia.org] meaning rock or crag (the same meaning as Peter).
(b) caption: " 'Chinese Customs Hart' was caricatured in Vanity Fair in 1894"
Chinese translation: "英国《名利场》杂志于1894年刊登了这幅赫德身穿汉服的画像。（备注：比照贝尔法斯特女王大学特藏线上展览，图中 '江海关' 呈倒置，但确实为画作正面。）"
(i) Vanity Fair https://en.wikipedia.org/wiki/Vanity_Fair (may refer to: Vanity Fair (magazines), any of five magazines: "Vanity Fair (British magazine), 1868–1914, famous for its caricatures [a weekly 'aimed to expose the contemporary vanities of Victorian society': Wikipedia]" + "Vanity Fair (magazine) (1983–present), a monthly American magazine of culture, fashion, and politics")

(A) Queen's University Belfast (public; opened in 1849 as "Queen's College, Belfast")
(B) Queen Victoria (reign 1837 – 1901)
(c) "Born in Portadown ['in County Armagh'] in 1835 to a middle-class family, the young Robert Hart grew up in the town and later in Lisburn before enrolling at the newly-founded Queen's College in Belfast, now Queen's University. At the age of 19 [1854], he accepted a job in Britain's Chinese Consular Service and set sail for Hong Kong, which by that stage was under British rule. ['1859年，赫德辞去领事馆职务、加入中国海关': zh.wikipedia.org for 赫德] * * * He then became Inspector-General of the Chinese Imperial Maritime Customs Service 海关总税务司 [based in Shanghai] * * * and held the post for 45 years."

(d) "Dr Weipin Tsai 蔡维屏 [(a woman)], a senior lecturer in modern Chinese history at Royal Holloway University in London, who is writing a book about Hart, says he had a genuine interest in China separate to other imperial administrators of the era. * * * In 1857 he began a relationship with a Chinese woman, Ayou [阿姚: zh.wikipedia.org], and went on to have three children with her. Their relationship, constrained by the customs of the time, wasn't to last and in 1866 [age 31] he arrived back in Britain on leave and married an 18-year-old, Hester Bredon, in Dublin. He had three more children with Hester but their relationship was far from perfect and she and the children returned to Britain permanently in 1882"
(i) Royal Holloway, University of London https://en.wikipedia.org/wiki/Royal_Holloway,_University_of_London
(was founded in 1879 by the Victorian entrepreneur and philanthropist Thomas Holloway [as] Royal Holloway College [which] was officially opened in 1886 by Queen Victoria as an all-women college [now coeducational]; became a member of the University of London in 1900)
(ii) One definition of "separate" as an adjective is "different." Still, I have found no example in Web dictionaries that contains "separate to." Maybe "separate from"?
