If the legal answer is “nothing,” the historical and human answer is the opposite. A scattered population of eight to twenty-five thousand quiet European citizens carries, in their mitochondria and on their Y-chromosomes, the genetic fingerprint of an entire vanished aristocratic order — an order that publicly insisted these children had never existed at all. The Recoaro convent journal is, in this sense, one of the most consequential surviving documents of the long 19th century: not because it changes any throne, but because it returns a previously invisible population to history.
For the Asnicar archive specifically, the implications are narrower but real. Several of the surrounding hamlets named in the journal — Rovegliana, Fongara, Parlati — are also the hamlets in which our documented ancestors were baptised, married, and buried. The probability that at least one Asnicar branch absorbed a foundling stipend during the Belle Époque is, statistically, quite high. The probability that any specific living Asnicar is the great-grandchild of a sovereign monarch is, of course, quite low — but the probability that the aggregate family carries that history somewhere in its collective genome is, mathematically, almost a certainty.
That is what this archive will continue to record. Carefully. With citations. And, for so long as it sits on the public internet, without ever naming a living person.
