Record Search

Direct links to lists of baptisms, marriages and burials for the Dumaresq family can be found under Family Records opposite. If you want to search for records for a spelling variant of Dumaresq, or for any other family name, just click below on the first letter of the
family name you are interested in. This will open a new tab in your browser giving you a list of family names beginning with that letter,
for which there are baptism records in our database of half a million church and public registry records.

You can also select marriages or burials. Select the name you want
and when the list of records is displayed you can easily refine the search, choosing a single parish, given name(s) and/or start and end dates.

The records are displayed 30 to a page, but by selecting the yellow Wiki Table option at the top left of the page you can open a full, scrollable list. This list will either be displayed in a new tab or a pop-up window. You may have to edit the settings of your browser to allow pop-up windows for www.jerripediabmd.net. For the small number of family names for which a search generates more than 1,500 records you will have to refine your search (perhaps using start or end dates) to reduce the number of records found.

New records

From August 2020 we have started adding records from non-Anglican churches, and this process will continue as more records, held by Jersey Archive, are digitised and indexed. Our database now includes buttons enabling a search within registers of Roman Catholic, Methodist and other non-conformist churches. These records will automatically appear within the results of any search made from this page.

Origin of Surname

The original Dumaresq came from swampy surroundings, for Maresq and Marest are both Old French for a marsh. It may well be that this is one of the few surnames of importance to have had their origins in Jersey rather than having been imported from France or elsewhere.

The name is not found in France today, nor are there any remaining Dumaresq families in Jersey.

Early records

This was one of the most important families in Jersey from the 13th century onwards.

A Jordan du Maresq was Jurat of the Royal Court in 1292 and a reasonably reliable descendancy can be traced from another Jordan, born in about 1300, and possibly his son, to the present day. (See below). Edouard and Richard Dumaresq are listed in the Jersey Chantry Certificate of 1550 but strangely the name does not appear in modern records of those in the 13th century Assize Rolls, which are a recognised way of establishing a rough date for the timing of the first appearance of a family name in Jersey.

However, the transcription of the 1274 Extente published in the late 19th Century by La Société Jersiaise shows that Peter and William du Marais were landowners in Trinity, Philippe du Marais is shown as an elector in Saint Brelade; William du Marais, Peter Maret, Luke Mareys, Philip des Mareys, and William des Mareys are all mentioned, as is Jordan du Marais in a case brought against parishioners of Saint Lawrence.

Sir John Dumaresq, 1869

From Payne's Armorial of Jersey

Few families in Jersey can boast a more lengthened lineage or more distinguished members than that of Dumaresq. It is one of the few patrician houses of the island, the representatives of which have, from the earliest historic period, held offices of trust and distinction in the public service of Jersey.

Falle, the historian, makes special mention of its rank and antiquity, and congratulates himself upon his connection with it.

The first insular settler of the name is stated to have been of a Norman family, and to have migrated in the suite of certain ecclesiastics who visited Jersey for the purpose of dedicating one of the parish churches, in the early part of the thirteenth century. The earliest official mention of the name occurs in a roll of the Exchequer, 21 Edward I, recording assizes held in Jersey, 23 November, 1292, in which Jordan Du Maresq appears as a Jurat of the Royal Court of the island.

The name has been variously spelt De Marisco, De Marais, Dumareys, and Dumarescq a name which was not, at one period, peculiar to the island; for in 1217 John De Marisco held the See of Durham, and in 1272 William De Mareys held lands in Oxford. There exists, however, no evidence to prove the common origin of the Jersey and English families.

That of Jersey appears primarily to have been established in the parish of Saint Brelade, where it held the estate of La Haule. So early as the reign of Edward II, William Dumaresq was Attorney-General of the island, and is justly remembered with admiration on account of his successful and able defence of the liberties and privileges of his countrymen before John de Fressingfield, Drogo De Barentine, and John De Button, the Commissioners appointed by the King to inquire into the legislative and jurisdictive state of the island.

From La Haule a branch settled at Vinchelez de Bas, of which fief it obtained the Seigneurie in 1486; whence, about 1500, John, son of Thomas Dumaresq, Seigneur of Vinchelez de Bas and of Gorge, by his marriage with Mabel Payn, the lady of Samares, removed to that Fief Haubert, which remained in the possession of his descendants for eight generations. Of this branch, Henry Dumaresq, Seigneur of Samares, was conspicuous for the support he gave to the Republican cause at the period of the Great Rebellion, when he was one of the Rebel Commissioners, and for his friendship for Michael Lemprière, the Parliamentarian Bailly of Jersey.

His son Philip, however, appears to have held opposite views, for he figures as a Jurat of the Royal Court very shortly after the Restoration. He was born about 1650, and entered at an early age the Royal Navy, where he rose to Post rank. He is well known as the author of a Survey of Jersey, which he presented to James II. in 1685. The original manuscript is preserved at the British Museum. His only daughter Deborah, who conveyed the Seigneurie of Samares to the Seale family, died without issue.

From the family at Samares sprang the various branches of Dumaresq du Morin, Dumaresq des Augres, with. others settled in various parts of the island.

The estate of Morin derives its name from a family once of some note in the island, but now extinct. Perrez Moryn was Lieuteuant-Bailly to Sir John Bernard in 1431, and Nicholas Morin was Bailly under the Count de Maulevrier in 1467. This branch of Dumaresq, now quite extinct, was allied by marriage to some of the best families of the island.

The fief of les Augres was acquired by this family by the marriage of Richard Dumaresq with Collette Larbalestier, its heiress. The family of Larbalestier is one of very early settlement in Jersey, and is said to have derived its patronymic from the fact of an ancestor having held the post of bow-bearer to the Conqueror. Of this branch was the Rev Daniel Dumaresq.

Another branch, several of the members of which are settled in England, is represented by the descendants of Lieutenant-Colonel John Dumaresq and of Philip Dumaresq, late President of the Council at Cape Breton. Its insular, no less than its English, alliances, together with its social position, render it the most prominent portion of this famous honse.

Jersey family trees

Despite the importance of the family in Jersey and, perhaps because of its early establishment, long before the days of church records of baptisms and marriages, several of the trees below are considered very unreliable. Our review of trees during 2018 and 2019 attempted to correct errors and expand the trees, drawing more on trees published online than would normally be our practice. Some of these trees remain with obvious inaccuracies and all should be researched together and treated with caution. We intend to review the whole Dumaresq family, which undubtedly had a common ancestor, when time permits, and create a definitive tree drawing on the others and including as much detail as possible

These first six trees all cover much the same lineage, the first two at great length, the others just featuring sections. There are discrepancies between the trees, which are lacking in dates and other details at key periods

The church record links above will open in a new tab in your browser and generate the most up-to-date list of each set of records from our database. These lists replace earlier Family page baptism lists, which were not regularly updated. They have the added advantage that they produce a chronological listing for the family name in all parishes, so you do not have to search through A-Z indexes, parish by parish.

We have included some important spelling variants on some family pages, but it may be worth searching for records for a different spelling variant. Think of searching for variants with or without a prefix, such as Le or De. To search for further variants, or for any other family name, just click on the appropriate link below for the first letter of the family name, and a new tab will open, giving you the option to choose baptism, marriage or burial records. You will then see a list of available names for that type of record and you can select any name from that list. That will display all records of the chosen type for that family name, and you can narrow the search by adding a given name, selecting a parish or setting start and end dates in the form you will see above. You can also change the family name, or search for a partial name if you are not certain of the spelling

The records are displayed 30 to a page, but by selecting the yellow Wiki Table option at the top left of the page you can open a full, scrollable list. This list will either be displayed in a new tab or a pop-up window. You may have to edit the settings of your browser to allow pop-up windows for www.jerripediabmd.net. For the small number of family names for which a search generates more than 1,500 records you will have to refine your search (perhaps using start or end dates) to reduce the number of records found.

New records

Since August 2020 we have added several thousand new records from the registers of Roman Catholic, Methodist and other non-conformist churches. These will appear in date order within a general search of the records and are also individually searchable within the database search form
