Carl Henrik Lind (1864-1949) was born to Malvina Eugenia Hildegard Gosselman (1844-1885) and a man whose name was only revealed to us 100 years after Malvina's death. My grandmother, Sally Elisabet Lind (Ericson) received a letter from a person in Sweden, who may or may not have been a family member, asserting "It can now be told" that Carl XV was the father of Carl Henrik Lind. I never saw the letter, and hope it will be among the papers of Sally's daughter (my mother) or her sister, both of whom in are their mid-90's.
Because of the letter, and my grandmother's belief that Carl XV sired her father, I decided to use the 6 photo portraits of Carl Henrik Lind at different ages, inherited from my grandmother, to create facial recognition comparisons with 8 photos of Bernadotte males of different ages. The results were astonishing, with an average facial match of about 73%. This is the exact same facial comparison match as that of the average of the same 8 Bernadotte males.
Through the DNA test my mother took, I was able to find a number of her Swedish cousins, including several descendants of Carl Henrik's brother, Henrik Casimir Lind, who was also in the Oatka birth records. I found that they too had heard about Malvina's 'secret'.
One problem with not being able to prove the identity of Carl Henrik's father is that my mother has many DNA matches for whom Geni can only find an "in-law" match. And, I learned recently that one particular DNA match is a Geni blue-line match to the current king of Sweden. I have no idea otherwise of how we could be connected. Yet, Geni can only find an in-law match from my mother to her.
I'd be interested to learn what other people think about whether photo-recognition matches should be usuable in solving family mysteries like my own. Also, how to solve the problem of DNA matches who should have a blue path, by do not.
