Old Norse Móðir (f.)
The Old Norse female name Móðir is found in Motherby, Cumberland, and has been suggested as the first element in Moodersley, a minor name in Kedleston, Appletree Hundred, Derbyshire. The name Kedleston itself includes the male personal name Ketill.
Móðir means literally ‘mother’ and the use of family terms as personal names (compare the use of ‘Sonny’ in English), while not frequent, is attested in Scandinavia.
