Fief de l'Eperon

In 1440, the Fief Blondel was transferred. In the deed, it specifies a certain fief called the fief Thomas Blondel being in the said parishes, parcel of the fief au Canely containing about three bouvées of land called the Bouvée Phlipot Pain, lying in the said parish of St Pierre du Bois, and the bouvées Torquetil and Bourgeon with the fief de l'Eperon lying in the said parish of Torteval and likewise all and such seigneuries, dignities, liberties, graces and franchises as to the aforesaid fiefs and each of them attach and belong with a certain dinner which the said Jenete takes and owns annually for an estate of inheritance, she claims, on the fief of the Prior of Lihou.  Translation by Dr. Ogier of Guernsey.

The 1440 deed shows that the  Fief de L'Eperon at Torteval was transferred with the sale of the Fief Blondel along with rights to such seigneuries, dignities, liberties, graces and franchises and dinners from the Fief of Lihou.

Historically, there several EPERON Fiefs. See: https://www.theislandwiki.org/index.php/Fiefs_of_Guernsey

1) Fief a Eperon or Fief de L'Eperon

2) Fief Des Eperons ( Seigneur Rougier and presently Seigneur Moullin Family.)

One of these Eperon Fiefs ( The small fief of:  Fief Des Eperon)  is still shown on the map of Guernsey between the Fief L'Eveque de Coutan ces and the Fief De La Rue Frairie.  This fief is not associated with Blondel and was owned by Seigneur Eric Bailleul Moullin (10 August 1893 – 18 September 1963)

Therefore, the 1440 Blondel Deed's Fief de l'Eperon of Torteval is independent and separate from the other Eperon fief which may be in St. Andrews Parish. It is recorded as a dependency fief of Blondel.

 The 1890 List of Guernsey Lords/Seigneurs only shows one Eperon fief in St. Andrews.  https://www.priaulxlibrary.co.uk/articles/article/lords-manors  Thus, the other Eperon at Torteval fief would continue to be a dependency on the Blondel Fief.

Guernsey Connections - Fief des Eperons
He was very proud of his Guernsey roots, and was a regular visitor to the island, and knew the island well.  He was a founder member of the Guernsey Society, and served as chairman from 1947-1949. He was a regular contributor to The Quarterly Review. Together with Herbert John Fleure and Freddie Priaulx, was a major contributor to The Guernsey Farmhouse, a book published by the Society in 1964 celebrating the ancient family houses in the island.

According to the History of Guernsy 1814 by William Berry, The parish of St. Andrew, which lies towards the southern extremity of the Island, is the only parish which is not at any part bounded by the sea, and consequently the incumbent has no tithe of fish. The parish is divided into La Grande and La Petite Vingtaine, contains about two thousand five hundred vergees of land, one hundred and twenty dwelling-houses, with a population of nearly seven hundred persons; and the number of quarters rated to public taxes is estimated at five thousand, the average rate per quarter paid yearly being about sixpence.

There are several fiefs within the boundaries. That of Maux Marquis contains two hundred and eighty-five vergees, twenty-five perches. The frank-fief of St. Helena, containing about two hundred and twenty-four vergees, is now may be in the possession of William de Jersey, Esq. famil and the manor-house will be found depicted in the annexed Engraving. The rectors of this parish have long held a field for the service of performing mass when the seignior of this fief holds his court; but since the Reformation, the Lord's Prayer has been substituted in its stead.* The fief Rohais, the property of John Allez, Esq. family containing two hundred and eight vergees, small measure, of thirty six perches to the vergee. The fief La Haulle, fifty-eight vergees, thirty-seven perches; and the fief Eperons. In the last extent, mention is likewise made of the fief De la Rue Friery, L'Evesque, and of the Abbess Caen, with the bordage of Alminack. Citation
