Origin of Surname
The Christian name was a pet name for Nicolas and developed as a surname. The name is found more in Guernsey than Jersey.
Collas appears in the Extente of 1528.

Payne's Armorial of Jersey
One of the most ancient houses of Britany is that of Collas, Seigneurs de I'Espine. At the disastrous battle of St Aubin-du-Cormier, Gratian Collas, of this family, being grievously wounded, was one among the many Bretons whose only safety lay in flight. He found, however, time and opportunity to carry with him his wife, and also some of his wealth, and, crossing over to the opposite coast of Jersey, took refuge in the parish of Saint Martin.
There, on 15 September 1490, he purchased, conjointly with Appaulina, his wife, the Maison de St Martin. As a striking instance of the integrity and simple faith of the islanders at that time, it may be mentioned that the contract referred to above was merely read at the foot of the high cross in the parish churchyard, which rendered the purchase valid. However, 20 years afterwards, it was deemed right to register the sale in the form of a deed, sealed with the broad seal of the island, and countersealed by Nicholas de Hamptonne, then Lieut-Bailly; which deed is still extant in the family.
From this spot the family has never removed, and the house, although rebuilt, occupies the site of its veteran predecessor.

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.
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
