Arwennack

Arwenack, historically in the parish of St Budock, Cornwall, is a historic manor on the site of what is today the town of Falmouth. It was partly destroyed in 1646, and only a remnant survives today. It was long held by the Killigrew family, which was responsible for the development of the town of Falmouth, Sir Peter Killigrew (died 1667), MP, having received a royal charter for its foundation in 1661.

Arwenack is said to signify in the ancient Cornish language either "the beloved, still cove", or "upon the marsh".

The earliest recorded lord of the manor of Arwenack was the de Arwenack family:

Simon Killigrew (fl.1377), married Jane de Arwenack, daughter and sole heiress of Robert de Arwenack. He was the son of John Killigrew of Killigrew, by his wife Mary Poltesmore, daughter of Sir Richard Poltesmore, and was the first of the family to hold Arwenack.

Thomas Killigrew, son, whose wife was a member of the Beaupell family (possibly Beauple of Knowstone and Landkey in Devon, the heiress of which Margaret de Beaupel, married Sir Neil Loring, KG (c. 1320 – 1386), one of the founding members and 20th Knight of the Order of the Garter, established by King Edward III in 1348). He had two sons:

John Killigrew, senior, of Arwenack, eldest son and heir, who married Mary Boleigh, daughter and heiress of John Boleigh. The Killigrews later quartered the arms of Boleigh: Argent, on a chevron sable between three torteaux as many bezants, as visible on the monumental brass in St Budock's Church to John Killigrew (died 1567) of Arwenack, first Governor of Pendennis Castle.

John Killigrew (died pre-1513), son and heir, who died with no sons, leaving a daughter and sole heiress Elizabeth Killigrew, wife of John Godolphin of Godolphin, Cornwall. The estates however descended to his younger brother as heir male under an entail.
