From "A history of the burgh and parish of Ellon, Aberdeenshire," James Godsman, 1958.
The Rev. Nathaniel Grieve, M.A. He was born in 1782, the son of John Grieve, Oldmill, parish of Turriff. In 1803, he graduated at Marischal College, Aberdeen, and in that year was ordained to the charges of Chapelhall and Tillydesk. For a period he was in charge of the congregation at Old Meldrum. In 1806, Mr Grieve married firstly, Miss Ann Pirie of Orchardtown, parish of Udny, and had issue:
John, a clergyman in the Church of England, who died in 1886. Mary, wife of James Wilson, M.D., Staff Surgeon; she died in 1891. Isobel and Helen, who died in childhood.
In 1815, he married secondly, Miss Sophia Robertson, 1790-1862, and had issue:
Alexander, M.D., Fraserburgh; he died in 1891. Nathaniel, M.A. Samuel, M.A., 1831-1895. Jane, married the Very Rev. Alexander Harper, M.A., at St Mary's, Inverurie, and Dean of Aberdeen. Sophia, died 1840. Elizabeth, died 1885. Margaret, and Jane, who died in childhood.
Mr Grieve carried out the plan which Bishop Skinner had much at heart, viz., the uniting of the two charges at Tillydesk and Chapelhall. A new church, built in 1816, at Chapelhall, on the south bank of the River Ythan at Ellon, was opened on Sunday, 28th July, 1816. The chapel was to have been opened by Bishop Skinner, but he died two weeks before this date, and the sermon which he intended using at the consecration, was read by Mr Grieve.
The first chapel at Craighall was a commodious oblong building with a small apse for a sanctuary, in front of which stood the "three decker pulpit,", reading, and clerk's desk, one above the other. The chapel was considered the best in the diocese. In 1862, improvements were made, but its bulging walls and general instability, marked its early demolition. Mr Grieve is described as "a worthy, good man, a good student, who left a valuable library." During his incumbency, Mr Grieve resided at Kinharrachie Lodge, in default of a Rectory at Craighall. In 1863, Mr Grieve retired to Aberdeen, where he died in 1866*, aged 84. He is buried in the Old Churchyard of Ellon, there being no burial ground at Craighall till the present St Mary's-on-the-Rock was built.
*Gravestone says 1863. Godsman sometimes makes errors, so you should always check the facts.
