Unlike many other surrounding villages, Dernbach has not a Franconian, but a Celtictoponym. Several communities and families have the same name, so it has become customary to say "Dernbach bei Montabaur", to avoid confusion.

History
Under its former name "Derinbach", the rural commune was mentioned in a document for the first time in 1220 AD. The medieval village structure was dominated by an impressive knight's castle and a much older chapel, built after 1136 AD in late Romanesque style. The knightly family of Dernbach, related to the noble House of Isenburg in terms of ministeriality, guarded and defended the nearby residence of the Archbishop and Prince-elector of Trier in Montabaur after his return from a Crusade in the Holy Land. As the male line of the family died, the famous Hilchen von Lorch inherited the Dernbach castle and owned it for almost 300 years. After the end of the Holy Roman Empire the medieval moated fortress in Dernbach was converted into a courtyard by the House of Nassau. The ancient chapel dedicated to St. Lawrence was demolished in 1901, when for the first time a parish church was erected in Dernbach. The famous assembly of sculptures which belonged to the chapel, the so-called 'Dernbacher Beweinung', a group made out of clay, was transferred to Limburg, where it now can be seen in the diocesan museum.
The village owes its popularity primarily to the extraordinary life and work of the blessed Maria Katharina Kasper. Born and grown up in Dernbach as a child of small farmers, she everywhere noticed the misery and distress of the fellow human being and she was not willing to accept this for the rest of her life. Whenever possible, she went to the catholic school, above all because of the religious education. As a young woman she founded a pious association of young people, to help those in need. Finally the child's vision of a monastic life generously serving the poor and the sick became real in 1851 AD, when she founded the first new congregation of sisters in the 1827 newly established diocese of Limburg. In the following years further stations were established in and outside of Dernbach. When the foundress died, the congregation Poor Handmaids of Jesus Christ had 193 branches all over the world. In the early 20th century the international religious order grew up to more than 4,500 nuns, in Germany, Netherlands, England, USA – just to mention a few countries. Maria Katharina Kasper was beatified on April 16, 1978 by Pope Paul VI, as the miracle needed for her beatification was reaffirmed. The motherhouse – today a modern building complex – houses the so-called , and the German provincialate, i.e. the order's administrative center for its province Germany. It is situated next to the Parish Church in the centre of the village. The order's current leadership consist out of sisters from India, Germany and the USA. On March 6, 2018, the Vatican announced the recognition of a new miracle. It ist said to have happened in 2011/12 at her intercession in India. She was canonized by Pope Francis in Rome on October 14, 2018.

Economy and infrastructure
Education
300 years of school history document the tremendous importance of education for Dernbach and its long-term development. The challenge of a growing population in the long run could be met by investing in classrooms and school buildings. The "Pfarrer-Giessendorf-Schule" from the 1960s, renovated just a few years ago, today is a primary school. Meanwhile, a private school is located at the site too.
