Numbers and Roman Figures indicating the Branches and Generations are follow those of the NP94 (Nederlands Patriciaat issue 1994).
Where (&) appears after a name: further details have been left out on request of that person.

From 2016 onwards the family name of the father of the wife/partner of a male Kolff will always be stated contrary to earlier practice where this name was omitted because already mentioned with the person concerned. The webmaster will gradually introduce this system to all genealogical details.

The former official name of The Hague has been ’s-Gravenhage. The Dutch official name for The Hague is now Den Haag. At the English language section I use The Hague, because the city is widely known as such.


Latest changes (births, marriages, deaths) since publication of NP94 are included when know by the association. This may result in incomplete information since not always all details are given.

Numbers I used in the Genealogy after 1994 may be differ from those used by the Netherlands Centraal Bureau voor Genealogie in a later edition of the Nederlands Patriciaat.

Family members are encouraged to report items that are not correct to the . Moreover I encourage anyone who knows more about relatives then we do, where we miss links, due to migration, etc., to let us know.

The historical ties between the Netherlands and Indonesia are tight, a connection more felt in the Netherlands (Holland) then in Indonesia. A very large part of the Dutch (Netherlands) population has ties with Indonesia, even though almost all of them nowadays live in the Netherlands. The Kolff Family is no exemption in this historical fact. Many Kolffs were born there, lived there (many of them all of their lives and they must never have felt any proper connection to Holland except for their ancestry). Some explication, more in detail, about the use of certain words has been considered necessary for this reason. This has been added because of the frequent appearance of these kind of connections within the genealogy.

On Indonesia (formar Dutch East Indies)

The city of Batavia (capital of the Dutch East Indies) is now Jakarta (capital of the Republic of Indonesia).

In other Indonesian location-names replace in the Dutch spelling - OE - for a - U - (Bandoeng becomes Bandung).
The same for: - DJ - is now - J - (Djakarta is now Jakarta),
or - Y - (Djokjakarta is now Yokyakarta).

In the Genealogy the spelling at the time of birth of the member of the family is used.

India or Indonesia

The Dutch East Indies are the present day Republic of Indonesia. Indonesia gained independence from the Netherlands in 1949 (after the declaration of independance in 1945). Nieuw Guinea, now Irian Jaya, remained under Dutch control until 1963 when it was incorporated in Indonesia. In Dutch (Netherlands) colonial times this geographical area was always referred to as Indië which would be translated into English as India. This at times may lead to confusion.

The Netherlands East India Army (Nederlands Oost Indisch Leger) is therefore not the same as the British East India Army. K.N.I.L. is the Royal Dutch East India Army (Indonesia); O.I.L. is the East India (Indonesia) Army.

Dutch family name prefixes and the use of capitals

Many Dutch family names have prefixes such as:
van, van de, van der, van ’t, ten, te, etc.

It is common use that capitals are only used at the first prefix when the Christian name or its initials are not used.

In alphabetical listings the prefixes are always ignored, family names are categorized on the noun after the prefixes. A name such as, Van den Heuvel, would be categorized under “H”.


In Belgium a family name as (Dutch spelling:) “Van den Heuvel” will often (but not always, depending on the choice of the family in previous times) appear as: Van Den Heuvel, categorized under “H”, or as Vandenheuvel, and subsequently be categorized under “V”.
In case in Belgium when the prefixes are written seperately, they use: Van Den Heuvel (all capitalized) in most cases.

Furthermore: In most other countries these names are often written as Vandenheuvel or VandenHeuvel.

Examples on use of capitals:    
The Netherlands   Belgium
John van den Heuvel  
Mr. Van den Heuvel  
Mr. John van den Heuvel  
Family Van den Heuvel  
Mr. J. van den Heuvel  
John Van den Heuvel, John Van Den Heuvel
Mr. Van den Heuvel, Mr. Van Den Heuvel
Mr. John Van den Heuvel, Mr. John Van Den Heuvel
Family Van den Heuvel, Family Van Den Heuvel
Mr. J. Van den Heuvel, Mr. J. Van Den Heuvel
Double Names which are One Family Name

Throughout the genealogy the Dutch spelling of family names is used. This may sometimes lead to some confusion in case of double names, and for that reason an explication on the ways double names are used internationally has been included here.
Several Dutch families have ‘double’ names, so have many of the Kolff’s: Van Santen Kolff, Kolff van Oosterwijk, Van Breda Kolff, and - rather recent - also Kolff Breymann.

In the Netherlands a double family name is never connected by: “ – ” as they are, for example, in England or Germany. So anyone named: Benthem Reddingius as the family name would never be hyphenated. If she marries a Kolff, her name would be written as: Mrs. Kolff-Benthem Reddingius.
Hyphens are used in Dutch family names, but only for women when they use their husbands name and their maiden name (as the example shows, and which is used very often; more about this at right).

In England or North-America this would be written as: Benthem-Reddingius. In this case, in the Netherlands, this would be read as: this is a female married to a Benthem and the female's maiden-name is Reddingius.

Contrary to general practise in the Anglo-American world Dutch women keep their maiden name, but it gets connected by a “ – ” to the husbands name that preceeds it (unless, nowadays under new legislation, they decide differently: e.g. the female keeps her maiden name as her family name, or, the husband - also legally possible - decides to take the wife’s name).

New legislation in the Netherlands may make things more confusing: in case of same sex marriages couples can choose the name they want to use. The Kolff Family Association follows Dutch legislation (see: Association: Regulations [most recent Regulations date from 2001]) in membership to the Association and inclusion in the Genealogy. This is one of the reasons why, in many cases, the children of female Kolffs now appear in the Genealogy: they are included when the family name Kolff has been choosen for them (according to Dutch law they can opt for change, once, when reaching maturity in order to enable them to decide for themselves).

Examples for double family names: (the use of Ms. has been left out of this schedule)
  Netherlands and international spelling: International, often also written as: Anglo-American examples:
Male married or not Mr. Van Santen Kolff Mr. Van Santen-Kolff
or Mr. Van Santenkolff
or Mr. Vansantenkolff
or Mr. VanSantenKolff
well, you see, there are many possibilities
Mr. Van Santen-Kolff
or Mr. VanSanten-Kolff
Female not married Miss Benthem Reddingius Miss Benthemreddingius
or Miss BenthemReddingius
Miss Benthem-Reddingius
She marries a Kolff Mrs. Kolff-Benthem Reddingius Mrs. Kolff-Benthemreddingius
or Mrs. Kolff-BenthemReddingius
or Mrs. Kolff
Mrs. Kolff
or Mrs. BenthemReddingius-Kolff
or any other spelling of her maiden name
here its the sequence which is important
On prefixes the same as written above applies to double names. Please note intentional use of ‘miss’, above.
