One possible origin of the Blakes of Wimbotsham:
*****
The original Welsh spelling of Blake was Aplake, meaning "the family on or by the lake." Other Gaelic Welsh spellings were Mcplake, MacPlake, and A'Plake. The Celtic spelling was O'Plake. Eventually the spelling of A'Plake changed to Blaake, and finally to Blake. The prefixes Ap and O' means "from son of..." The Blakes of Galway, Ireland were one of the fourteen tribes of Galway.
Richard Cadel, a feudatory of the Earl of Ulster and Lord of Connaught, Richard De Burgh, migrated to Galway from Wales before the year 1277. In 1277, the sixth year of his reign, King Edward I knighted Cadel "Sir Richard Blake." Cadel assumed the surname Blake and was the ancestor of all the families of Blake in Connaught. However, for many generations they used the name Caddell as an alias.
In 1278, the castle and lands of Kiltorroge, castle and land of Sallin'croe (now Carmore) located in Dunkellin County, Galway were granted to Cadel by De Burgh. By 1315 he had received the lands and manor of Kiltullagh. Eveline, his wife, was the mother of four sons: Walter, John, Niicholas, and Valentine. Records have been documented of this line to 1878 in Ireland. Thus Richard Cadel is considered to be the progenitor of all the Blake descendants.
