I agree with Cynthia. There is no publicly known portrait of the Marchioness of Carisbrooke with this fringe. The last known wearer of it was Princess Beatrice.
Her daughter Ena was pictured with countless different tiaras, but not with this one. Besides, she sold much jewellery during her exile. If she inherited this one, it must have been sold or it would already have been seen on her descendants.
The strawberry leaf tiara was sold as well. So there is not much hope that this tiara is still with Beatrice's descendents.
