In 1930 a new parish of Nordelph was created in Downham RD, taking land mostly out of the Marshland RD parish of Upwell.[2]
Several changes were made to its boundaries in 1935. In particular, it took in four large (in area terms) parishes from the disbanded Thetford Rural District.
In 1974, the district was abolished under the Local Government Act 1972, and became part of the West Norfolk district, renamed King's Lynn and West Norfolk in 1981.
Welney Rural District
Welney Rural District[3] was (at least nominally) a short-lived entity created in 1894 containing the only parish, West Welney, which had been in Downham RSD but lay in the Isle of Ely rather than Norfolk. Its population at the time was about 500.[4] In 1895 the parish was transferred to Norfolk, and Welney RD was absorbed by Downham RD. There does not appear to be any evidence that it ever actually functioned.[5]
