LONG-GROVE, or LLANGROVE, formerly a hamlet of Llangarren, was in 1856 formed into an ecclesiastical parish. It is distant 1 miles S. of Langarren, 6½ S.W. of Ross, 4½ N. of Monmouth, and 15 S. of Hereford; is in Wormelow hundred (lower division), Ross union and county court district, Whitchurch polling district, and Harewood End petty sessional division. The population in 1861 was 742; in 1871, 573; inhabited houses, 127; area of ecclesiastical parish, 1,570 acres. Sir Joseph Russell Bailey, Bart., M.P., who is lord of the manor, Mrs. Marriott, and John Jones, Esq., M.D., are the principal landowners. The soil is sandy and loamy; subsoil, chiefly sandstone rock; products, wheat, barley, roots, &c. Long-grove is in the diocese and archdeaconry of Hereford and rural deanery of Archenfield; living, a vicarage; value, £105, with residence and 2 acres of glebe; patroness, Mrs. Marriott; vicar, Rev. George Wowen Jones, M.D., of St. Peter's College, Cambridge, who was instituted in 1857.

The church, called Christ Church, was built in 1858, at a cost of £1,500, solely defrayed by Mrs. Marriott, of Sellarsbrooke, the lady of the manor of Goodrich. It is in the Early English style of architecture, and consists of an aisle, nave, chancel, and vestry, with a bell-turret. The walls are of grey stone range work, with Bath stone dressings. The font is of Painswick stone. The whole area of the church is floored with red and black square flooring bricks. The communion table, on which is a green cover, with varied fringe, is of oak, of which material the pulpit, reading-desk, lectern, stalls, seats, communion rails, &c., are also composed. The window in the chancel is of stained glass, with scriptural representations. The other lights are chastely executed, and surrounded with stained glass of a variety of tints. The building is warmed with one of Grundy's patent ventilating hot-air stoves.

The silver communion service is the gift of the late T.W. Booker Blakemore, Esq., M.P. The accommodation provided is sufficient for 300 persons - all the sittings being free and unappropriated. The church and burial-ground, which are enclosed within a substantial wall, occupy three-quarters of an acre. The architect was Mr. Bodley, of Brighton, and the builder, Mr. Roberts, of Monmouth. A new schoolroom was erected in 1872 at the sole expense of Mrs. Marriott, and in 1874 a residence for the master was also built. The school is conducted on the national system, and is under government inspection; average attendance of boys and girls, about 60. There are Congregational chapels at Ruxton and Long-grove. The Wesleyans have chapels at Long-grove common and Llancloudy. Trewen, 1 mile S.E., Treworgan, 1 mile N.W., Penblaith, 2 miles W., and Llancloudy, 2 miles N.W., are places here.
