Ainderby Miers with Holtby is a civil parish in North Yorkshire, England.[1] The population taken at the 2011 Census was less than 100. Information is now kept with the parish of Hackforth. However, in 2015, North Yorkshire County Council estimated that the population of the parish was 20.[2] The parish is bounded to the east by the A1(M) motorway,[3] and is about 3miles south of Catterick, and north of Bedale.[4] It includes the hamlets of Ainderby Miers and Holtby Grange.
Ainderby occurs three times in the area (Ainderby Quernhow, Ainderby Steeple, and Ainderby Miers). The first part is derived from a personal name, Eindriði, and the second part denotes the area: Quernhow was where the quern-stones came from, Steeple denoted the church, and Miers denoted that the land there was boggy (a mire).[5]
