Extracts from: "The Wedgwood Circle 1730-1897 - four generations of a family and their friends." by Barbara and Hensleigh Wedgwood 1980:

The first Wedgwood of significance was Josiah (1730-1795), he started the pottery business in Staffordshire, and was succeeded by Josiah Wedgwood II (1769-1843). The next generation included Hensleigh Wedgwood (1803-1891), and here we are given a very brief mention in the early 1870s of "another of the Hensleigh Wedgwoods' friends [ie friend of the family], Francis Newman." (p.298) - unfortunately that's all we are told, though Francis Newman was the President of the Vegetarian Society at that time.

It is worth mentioning in passing that Hensleigh's sister, Emma, married Charles Darwin (whose mother was another Wedgwood...), and Darwin's close relative was the composer, Ralph Vaughan Williams - none of them vegetarian, but a well connected family.

The next reference is in the 1880s referring to Hensleigh's daughters (or more famously Darwin's nieces): Frances Julia (aka Snow 1833-1913); Katherine Euphemia (aka Effie,1839-1934); and Hope (1844-1935) :

pp324-6: "Effie and Hope carried their father's spiritualism one step further and joined the Theosophical movement. The Theosophical Society had been founded in America in 1875 by Madame Blavatsky, whose book The Secret Doctrine quickly spread the movement round the globe. .... G. B. Shaw ... attended meetings. Annie Besant ... in 1891, after the death of Madame Blavatsky, ... elected international president.

"Effie and Hope were both thrilled by Annie Besant's charismatic personality...

"In further pursuit of self-awareness, Hope became a vegetarian .... both Theta [Thomas Henry, Lord Farrer 1818-1899, Effie's husband] and Effie then became vegetarians. Theta's health improved.

p.337: "Hope ... following in the footsteps of her mother and grandmother, took an active part in the Society for the Prevention of Cruelty to Animals. She was at that time mounting a campaign against blood sports and was greatly opposed to dogs that were trained to hunt and kill.

p.354: "Snow Wedgwood ... leaving a large share of her fortune to the Anti-Vivisection League"

- and that's all we get, apart from a photo in front of one of the family's many large houses (Godfrey Wedgwood was Hope's cousin and husband):

Note: the three sisters above, also had a brother, Alfred, who is not mentioned in the book, other than being listed on the family tree. Alfred's son was James Ingall Wedgwood (1883 - 1951) who became a Bishop in the Liberal Catholic Church - the Theosophists. It is very likely he was vegetarian, as were most Theosophists, but we can find no confirmation of that.
