The 16-year old Anna Silfverschiöld is the only child of Baron Carl Silfverschiöld and granddaughter of Princess Desirée of Sweden. As such she's the probable heir to the two castles of Koberg and Gåsevadeholm and extensive estates in Sweden and Latvia.
When her grandfather, Baron Niclas Silfverschiöld, died in 2017 it was revealed that he had disinherited his two daughters, Héléne Silfverschiöld and Baroness Christina De Geer af Finspång, but also that they would be compensated in his wife's will. Since his death meant the dissolution of the old family entail there were certain conditions that had to be met when dividing the entailed properties which his and his wife's arrangement bypassed with the approval of their children. Furthermore the will stated that also his personal fortune went to his son and that should his son have sons it was his wish that the elder of them should inherit the family estate.
Edit: I didn't realise that this thread was specifically about most eligible men, but why not shake it up a little and add some eligible ladies as well.
