Some famous residents of St Nicholas-at-Wade include the following. The village connections of the Bridges family and TJ in particular were celebrated on 28 June 2003 in 'Bridges Between Nations', the Sixth John Briggs Memorial Lecture, at which Ben Jones (grandson of TJ) and Lord Bridges (grandson of Robert Bridges) both spoke, and international soprano Christine Hubbard sang some songs with words by Robert Bridges.
Molly Bernhard-Smith, founder of the XXI Gallery. She was well-known in artistic circles in the first half of the 20th century, and frequently brought guests to St Nicholas, many of whom stayed (e.g. Lionel Crane, son of Walter Crane). Her husband, Arthur Bernhard-Smith, was a ship's doctor but better known for his practical jokes; here are some newspaper clippings about his Meteor, Blue Grotto and Demeter escapades.
Dr Thomas Jones, C.H. ('TJ') joined the Cabinet Secretariat on its formation in 1916 and remained as Deputy Secretary until 1930, under 4 Prime Ministers, Lloyd George, Bonar Law, Baldwin and Ramsay MacDonald, during the period of the Irish Settlement and the General Strike. He wrote prolific diaries which shed much light on what happens behind the scenes in Whitehall. He came from the Welsh mining village of Rhymney and also devoted much energy to Adult Education, founding Coleg Harlech. In 1924 he built Street Acre in Shuart Lane, St Nicholas-at-Wade, which has continued to be the family home.

The Curling family lived at Shuart Farm, before emigrating to Van Diemen's Land in 1822, as told in the book Thanet to Tasmania.
John Hobbs, Wesleyan missionary to the Ngāpuhi tribe (Māori cannibals) of New Zealand, and a talented linguist, organist, builder and explorer. His descendant Tolla Williment wrote a fascinating biography, which only mentions Thanet and St Peter's, not St Nicholas-at-Wade specifically, but we know he worked as village blacksmith in 1819/20, living in The Forge.
Although he does not seem to have been a resident at any time, it's interesting to note that on 13 June 1948, Dylan Thomas introduced the BBC radio programme "Country Magazine" live from the Bell Inn. There is a fascinating article about this broadcast (check out the linked local press coverage too).
Finally, judging purely on the basis of the "number of column inches in the world's press" (primarily USA), the most famous residents appear to have been dogs. Out of over 300 articles mentioning St Nicholas-at-Wade on newspapers.com, over 50 of them refer to a single incident in 1955 when "Woo Woo" (actually Bow-wow), the dog of "Mrs Triston Jones" (actually Tristan: son of TJ above), fell down a 40-foot unused sewer and was rescued four days later by Ross Baldock, whose own dog "Bella" had fallen into the same hole. The next most popular mention is Sofer Whitburn's greyhound "Wise Counsellor", who died of exhaustion (the hares' revenge?) during a coursing meet in 1930.
