In the Domesday Book the manor is listed as part of the Doddingtree hundred, which covered areas of today's Herefordshire and Worcestershire.

The manor in the Domesday Book is listed as "Edevent", and "Gedeuen" from the Old English meaning 'fen or marshland of a man called Gedda'.

In 1393 the manor was conveyed with a carucate (area) of land to Roger Mortimer of Tedstone Wafer, with Hugh de Hawkesley acting as trustee.

Edvin Loach was acquired by Lord de la Warr, whose son, Sir Thomas de la Warr, sold it to Sir Humphrey Coningsby in 1528, who also held the manor of North Piddle, whereby both manors were passed down in the Coningsby family until 1657–8, when Edvin Loach was sold to Sampson Wise.

It was part of the Bromyard Union—poor relief and joint parish workhouse provision set up under the Poor Law Amendment Act 1834.

The parish church, dedicated to St Mary, was described as an "old stone building" with a bell turret, chancel and porch, of Saxon in part.

The ecclesiastical living was a rectory, with 34 acres (14 hectares) of glebe—an area of land used to support the parish church and priest—and a residence which was in the gift of Edmund Higginson, the principal landowner.

This church had been superseded for worship by an adjacent new St Mary's, built by Sir George Gilbert Scott, at the expense of Edmund Higginson, described as a ""handsome stone edifice, with apsidal chancel, nave, and spire".

The living was at that time united with that of Tedstone Wafer, in the gift of William Barneby of Saltmarshe Castle and Clater Park, who was also lord of the manor and principal landowner.

The old St Mary's church had an additional description noting the "remarkable amount of herring-bone masonry [and that] over the entrance door is a rude tympanium [and] the windows are of very early date, and there is an ancient font with Norman work on the base".

By 1895 Edvin Loach ecclesiastical parish had transferred to the rural deanery of Burford (east division) and the archdeaconry of Ludlow within the Hereford Diocese.

A Local Government Board Order of 1884 had transferred land, as Combe's Wood, from Edvin Loach to neighbouring Collington.

By 1913 the ecclesiastical parish was within the Bromyard rural deanery and archdeaconry and diocese of Hereford, and part of Tedstone Wafer was still annexed to Edvin Loach.

[16] Adjacent parishes are Collington at the north-west, Tedstone Wafer at the north and north-east, Norton at the east and south, and Edwyn Ralph at the west.

The parish is rural, of three farms, fields, managed woodland and coppices, water courses, lakes and ponds, and residential properties.

[16][21][22][23][24][25] Edvin Loach and Saltmarshe is represented in the UK parliament as part of the North Herefordshire constituency, held by the Conservative Party since 2010 by Bill Wiggin.

In 1974 Edvin Loach and Saltmarshe became part of the now defunct Malvern Hills District of the county of Hereford and Worcester, instituted under the 1972 Local Government Act.

The central east entrance has a first floor gabled projection as extension to the upper level, supported to the ground by oak posts.

The tower pointed arch is supported by large free-standing columns, with foliate details on each corner of the capitals, inset from the nave walls.

The Norman Romanesque south doorway of grey Tufa limestone, has, above its "massive lintel", a relieving semi-circular arch and tympanum.

[50][51][52] The old and new church are on the site of a previous Motte-and-bailey castle, as earthworks and buried remains, these at the highest part of the parish—600 feet (180 m)—today a scheduled monument.

It dates to the mid-19th century, of polygonal footprint, walls of stonework coursing with crenellated parapet, and two-light sash windows within stone mullions with squared hood moulds.

[57][58] Steeples (grid reference SO6649458156), at the southern border with Norton, is a 17th-century tile-roofed stone rubble house, orientated north to south, with a timber-framed cross wing each end.

At 220 yards (200 m) north from Steeples on the same road is Finches Cottage (grid reference SO6650658358), a 17th-century house, previously listed as a barn in 1973, timber-framed with brick nogging infill, tile-roofed with two dormer windows, an end-attached brick (listed as stone), chimney stack at the east, and a central gabled porch at the south.
