Origin
Oldest know family member to use the coat of arms is Rev.
Wolter Kolff (IX) (see also: History:
Geography: From Gelre to Holland), according to the coat
of arms of alliance between him and his wife, dated 1671 (in
family archives). Within the sheeld without colours he used
the three hammers (kolven, colven, or Kolffen), bats down,
outer two inclining inwards, the middle one inclining to the
right. As tarpaulin he used the swan.
Cornelis Kolff (Xc), notary public at
The Hague, used the top coat of arms, including the swan,
but standing and declining, to seal his documents (1704-1710).
(The Hague Municipal Archive, Notarieel archief, inv.nrs.
1695 and 1696).
