in the Delta 98 Den Haag collection:
an antique wax seal stamp with a coat of arms of a 1600-1750 era design, with on the shield / escutcheon and as crest
three ostrich feathers
the ostrich feather is an important heraldic symbol due to it's occurence in the heraldic devices of the English Royal family since the time of Edward the 3rd (1312-1377), it symbolised faithfulness, magnanimity, generosity and justice
we relate this seal and coat of arms to the Dutch family
with a coat of arms of three ostrich feathers emerging from a pot, a family name that, after becoming extinct, went on in the name
possible other ways of writing, or documented:
Geisteranus, Gheisteranus, Geesteren
and to John of Bohemia / Jean de Boheme et de Luxembourg,
According to the longstanding but now discredited legend, the Black Prince obtained the badge from the blind John I of Bohemia, against whom he fought at the Battle of Crécy in 1346. After the battle, the prince is said to have gone to the body of the dead king, and taken his helmet with its ostrich feather crest, afterwards incorporating the feathers into his arms, and adopting King John’s motto, “Ich Diene”, as his own. The story first appears in writing in 1376, the year of the Black Prince’s death. There is, however, no sound historical basis for it, and no evidence for King John having used either the crest (he actually bore a crest of vultures’ wings) or the motto.
Since a key factor in the English army’s victory at Crécy was the use of Welsh archers, it is also sometimes said to have been Edward’s pride in the men of Wales which led him to adopt a symbol alluding to their assistance. The German motto “Ich Dien” (“I serve”) is a near-homophone for the Welsh phrase “Eich Dyn” meaning “Your Man”, which might have helped endear the young Black Prince to the Welsh soldiers in particular. Again, however, there is no historical evidence to support this theory
we’ll stick to the Geesteranus origin...
