I thought it could be princess Ingeborg too and I've found this picture of her where she's wearing an unknown tiara and two of the stars queen Louise, princess Helena and Alix zu Castell-Castell have worn as a tiara.
Other princesses born in 1878 are princess Alexandra of Edinburgh, Isabelle of Orléans and Elisabeth of Austria but it doesn't seem to be one of them.
--Previous Message-- : Princess Ingeborg was born in 1978, and I : think that there is a similarity. But the : tiara is completely unfamiliar to me. Could : it be her? : : --Previous Message-- : Can anyone recognize this Princess? The : painting was done in 1896 when she was 18 : years old...so she was born in 1878..Do we : know of any Princesses being born in : 1878...maybe her tiara can give away who she : is?....Thanks again : : : : :
