I agree that Herlind is most likely to be the daughter of Adolf and his niece Geli and that when she was 6yo she was photographed with Adolf.
But lets go back to Adolf's mother Klara. There is only one photograph. She looks a lot like Mary Vestera including her ear which is better for identifying than general facial features. I believe Klara is in fact Mary.
Mary was the daughter of a Baron and mistress of Crown Prince Rudolf Habsburg. He shot himself in a famous incident called the Mayerling incident which happened at a hunting lodge in the forest. Would Mary, who adored Rudolf (meaning famous wolf) name her son Adolf (meaning noble wolf)?
Now supposedly the 17yo Mary also died at Mayerling. There are lots of photos of this young lady on the web. But many believe she was 6 months pregnant and that is why Rudolf shot himself in January. Then Mary was taken off in hiding and 3 months later in April gave birth to Adolf.
But back to Mary and her photos. One is curious because it shows a large lunar crescent in her hair like the moon goddess Diana. We know that the Habsburgs are satanists. Why would a satanist shoot himself? Or be shot by family? As a sacrifice in a ritual, perhaps?
A well-known ritual that they do is the Babalon working which Aleister Crowley described in his book Moonchild. They try to impregnate a woman in a ritual when the priest has summoned Satan and is possessed. But who was the man? Just because normal people see a powerful prince and his mistress and jump to conclusions does not mean it has any connection to reality. Rudolf's best friend was Philip Saxe-Coburg-Gotha. Could he have been the father? Hopefully you know that the family branch in England changed its name to Windsor. And that Queen Victoria had some kind of plan that saw her bloodline ruling Russia and Germany at the time of WWI. So was Hitler part of the Illuminati plan so that the Windsor bloodline would maintain control of a united Germany (with Austria and Sudetenland) after deposing the Habsburgs from power? And now once again, the same bloodline of Hitler is in a position to rule all of Europe.
Very odd things.
But there is more. Where did Angela Dorothea Kasner get her middle name? It just so happens that the name Dorothea is found in the Saxe-Coburg-Gotha family. I haven't yet followed up Philis ancestry to see which female ancestor was Dorothea. And it is possible that Philip vsited Rudolf with a cousin who ended up fathering Mary's child.
Looking at early photos of Queen Victoria I can see that it is possible she is related to the young Merkel or to Mary Vestera. Also, the history of the Vestera family is not that clear. Because these people often place children in foster relationships it is actually a possibility that Mary Vestera was already a Saxe-Coburg-Gotha.
And then there is Megan Markle. Linguists may enjoy looking into the etymology of Merkel and Markle. It involves Latin Marcus, Hebrew Malachi and Semitic Mu-Lik or person who rules, holds the whip
