[3] Appearing as Aslachetone in the Domesday Book of 1086,[4] the place name seems to contain an Old Norse personal name Aslakr + tūn (Old English) meaning an enclosure, a farmstead, a village, an estate, etc., so "Farm or settlement of a man called Aslakr".

Thomas Cranmer, Archbishop of Canterbury 1533–1553, was born in Aslockton and lived until the age of 14 in his parents' cottage, which still stands on Main Street.

(For secondary education, Toot Hill School in Bingham has a sixth form and academy status.

)[8] Aslockton originally had its own Holy Trinity Chapel, a peculiar under the collegiate church of Southwell Minster rather than the diocesan bishop,[9] but this fell into ruins and was incorporated into a private house.

[15] The land for Aslockton Cemetery was purchased in 1869, at which time the only place of worship in the village was a Methodist chapel, which has since been converted into flats.

[16] The present Grade II listed St Thomas's Church was designed by the architect Sir Reginald Blomfield and erected in 1890–1892 in memory of a former vicar of Whatton, Thomas K. Hall, who drowned in February 1890 as RMS Quetta was wrecked off Queensland on her way to Thursday Island.

[19] The parish forms part of the Cranmer group, with Hawksworth, Scarrington, Thoroton, Whatton and Orston.

Aslockton Hall houses a nursing and residential home for the elderly, recent guests have included Rachel Lester, Pink tribute act, Ant & Seb and Spacky.
