The history of the last name DeLap

The surname DELAP is believed to have originated in England, possibly in the counties of Derbyshire or Staffordshire, during the medieval period. It is thought to be derived from the Old English words "dell" meaning a valley or hollow, and "hop" meaning a small enclosed valley or enclosure, suggesting that the name may have referred to someone who lived in or near a small valley.

One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it appears as "de la Hupe," indicating its Norman French origins. This spelling variation suggests that the name may have been introduced to England by Norman settlers following the Norman Conquest in 1066.

In the 13th century, the name appears in various records as "de la Hop," "de la Hupp," and "de la Hup." By the 14th century, the spelling had evolved closer to its modern form, with instances of "Delap" and "Delappe" being recorded.
