The English surnames of Capel and Capell are derived from the Norman surname of deCapelle, as first recorded for Sir Richard deCapelle, a Norman knight with fief in County Hereford. He bore arms at Dunstable Tournament of 1308, "argent chevron gules among three torteaux," suggesting he was knighted before this time. His father was named by Henry III (1216-1272) to his viceroy as Lord Justice over Ireland. His ancestors immigrated with the Conqueror, according to most noble peerages of England. The Norman surnames deCapelle and LaChapelle referred to "one who is of the manor house," implying the nobility of this line in France.
Caple(s)later evolved as a phonetic variant, often interchanged in Capel and Capell lines, as well as forming inception of this surname. Since Norman deCapelle antecedents inhabited many other areas of Great Britain and Europe, phonetic and lingual variants were developed. Despite these phonetic and lingual variants, their inception is from the Norman deCapelle and nobility preceding William the Conqueror.
