The advowson of Mogerhanger was originally owned by Mrs. Dawkins who built both church and vicarage as a memorial to her husband, Rev. Edward Henry Dawkins, Lord of the Manor, who died in 1859. The advowson then passed with the Manor to Richard Mercer in 1888 and Mrs. V. Fane in 1909. When manors were abolished by successive Law of Property Acts in the 1920s the advowson passed to the Bishop of Saint Albans.

Since 1998 Mogerhanger has been part of the Ivel Group Ministry. This means that it shares a parson with Cople and Willington, the Vicarage being in Cople. Each church, however, retains its own Parochial Church Council, churchwardens and other officers as well as having its own services.
