The following chronological list of boundary changes is far from comprehensive, but should help those of you researching in these areas to track down those elusive records.
1844  The parish of Thorncombe was in Devon until transferred to diocese of Salisbury in 1836 and finally to the county of Dorset in 1844. At the same time the parish of Holwell, an island of Somerset territory surrounded by Dorset, was transferred to Dorset.
1896  The parishes of Goathill, Poyntington, Sandford Orcas, Seaborough, and Trent were transferred to from Somerset to Dorset, and Wambrook was transferred from Dorset to Somerset. In the west of the county, Chardstock was transferred to the county of Devon, but remains in the Diocese of Salisbury. 
1984  The County of Dorset was expanded to include Bournemouth, which had until then run its own services, and Christchurch, together with parts of the surrounding district was transferred from Hampshire to Dorset. 
1997  The Borough councils of Poole and Bournemouth became unitary authorities. However for ceremonial purposes both Poole and Bournemouth are to be regarded as part of Dorset.
