Yarm / Iarun / Jarun / Jarum / Yarme / Yarome / Yharum

There is an entry for Yarm [variant spelling] in the Domesday survey [https://opendomesday.org/place/NZ4112/yarm/] [accessed 20 December 2019] but it mentions neither cleric nor church in it. Whellan's History and topography of the city of York; and the North riding of Yorkshire (Beverley, 1859, vol. 2, p. 174) reports: "The massive font is rectangular with plain shields on the sides". The entry for this parish in the Victoria County History (York North Riding, vol. 2, 1923) notes: "With the exception of the west end, which is of 12th-century date, the whole of the church was rebuilt in 1730 [...] The font consists of an octagonal bowl of Tees marble with incurved sides, on each of which is a blank shield, and is apparently of 15th-century date." The VCH entry mentions some pre-Conquest findings in the churchyard: "a pre-Conquest coped gravestone found on the site of the grammar school in the present churchyard and probably belonging to the ancient church", but it also notes that "Until the 19th century Yarm was a chapel to Kirkleavington [...] The fact that the chapel had no parochial rights may account for the popularity of the Black Friars, who had a church here", which seems to be in contradiction of having a font of the 15th century in it. Morris (1931) notes: "The font is probably 15th cent." Noted in Pevsner (1985): "Font. Late Perp[endicular], concave-sided, with shields. -- The Font Cover must be Jacobean, although the knob is C18." The entry for this church in Historic England [Listing NGR: NZ4163312914] notes: "Rebuilt 1730 after a fire but containing some Norman masonry [...] C15 font with C17 cover. Some fragments of Saxon sculpture. C14 pair of effigies."
