Hi there Hilary
The Fownes, originally Fones and various other subsequent spellings, are an old family, seemingly Norman, settling in Saxby, Lincs after 1066. Considerable information is available at
www.fones.org and particularly at
www.fones.org/EnglishFones.html.
In the 16th century there was a migration by part of the family to the south-west of England, via Worcester, Bristol, Plymouth, Whitley finally to Kittery Court occupied by John Fownes, d. 4 Oct 1731. He as you probably know married Anne Yarde in 1681.
An important part of this line proceeded with the Reverend Thomas Fownes of Kittery Court (1730 to 1808) the grandson of this John Fownes. He married in 1764 Anne Vanham Somerville, daughter of Col the Hon George Somerville, son of James 12th Lord Somerville. Thomas Fownes and Anne produced, inter alios, James Somerville Fownes (1769-1848). He inherited from his uncle, the Reverend William Fownes, the Dinder estate, (Wells, Somerset) which had come to the Somervilles when George Somerville married Elizabeth Hicks, daughter of Robert Hicks of Combe, Gloucester, and Lord of Dinder Manor.
To keep the Somerville name associated with the estate and, I think, in respect to a wish of his benefactor, James Somerville Fownes somewhat unimaginatively changed his name to James Somerville Somerville. Thus subsequent Somervilles have mostly borne the name Fownes as well, as I do myself.
John Yarde Fownes married twice more after the death of Margaret Roope: Hannah Curtis in 1805, who bore him four children, and Nancy Hearn in 1816, who bore him two more.
The Roope name appears again in my family. Lt Cmdr Gerard Broadmead Roope RN VC (1905-1940) was, if I have it right, my first cousin, twice removed.
I did not know about and am sorry to learn of the destruction of Kittery Court.
