[2] In 1917 she married George Rudkin from Folkingham,[3] and according to her obituary in Folklore had "a blissful but tragically brief marriage until his early death in 1918".

[2] George had served as a commissioned officer in the Machine Gun Corps during the First World War and died in the influenza epidemic.

[7] Folk music was an additional interest of Rudkin's and she collaborated with Robert Pacey on A Lincolnshire Songbook.

[10] In 1952 she published a copy of The Later Bassingham Plough Play, which she worked on from a manuscript held in the North Lincolnshire Museum.

[2] By the time of their move to Toynton All Saints, Rudkin had such a large collection of objects that she had to rent a windmill to store them.

Initially Rudkin's book Lincolnshire Folklore was not popular, but over time it came to be appreciated; when it was re-published in 1976 by E P Publishing, it sold out immediately.

[2]In 1938, Rudkin published what became a seminal paper on the mythology of the Black Dog in Lincolnshire and is one of the most complete for any region of England, including songs, sightings and folktales.

[31] The academic study of the Harry Potter series has also drawn on Rudkin's work on the Black Dog motif.

[36] Holdings at North Lincolnshire Museum consist of archaeological and historical objects she collected, these include: a Neolithic jade axe from Wroot; witch balls; and a hobby-horse from a plough jag team.

[39] Many of the large objects collected by Rudkin are at the Museum of Lincolnshire Life, which began to be acquired in 1966 by curator Brian Loughborough.
