... della Ratta

this "..." profile was created to attach a line from the 1700s, whose tombstone of contessa Iulia de Racta, di Caserta leads to this knot.

She was mistakenly attached directly to Antonello with a time span of 300 years /!\

Marco's son based purely on the info of a "Marco ghost bugged profile" (deleted by user) where it was written:

Figlio di Antonello de Racta e Margherita Marzano 

da cui discendono i marchesi "de Natale Sifola Galiani"
