A renowned member of Boole’s social circle was George Everest (1790–1866), famous in his day as the surveyor general of the Great Trigonometric Survey of India and now remembered for unwittingly lending his name to the peak he more modestly called Peak XV. Everest was also a student of Indian culture and conveyed that interest to others, including Boole. Boole went on to marry Everest’s niece Mary, a writer and thinker working in the newly emerging field of education.
So much depends on random connections between people.
I suspect it's less random connections than being associated with the Royal Society.
https://en.wikipedia.org/wiki/George_Everest says "about 1825, he came to England for two or three years, and made a fast and lifelong friendship with Herschel and with Babbage" and "Everest was elected as a Fellow of the Royal Society in March 1827".
https://en.wikipedia.org/wiki/John_Herschel says in the 18-teens, Herschel "became friends with the mathematicians Charles Babbage and George Peacock" and "in 1821 the Royal Society bestowed upon him the Copley Medal for his mathematical contributions to their Transactions'.
