My mother-in-law spoke many times about rhe Abuzzi connection for the Iacobucci side of the family although when they immigrated, it was from Chiauci in Molise.
Today these are not very far apart in terms of how we travel. In the 1800s, this was quite a distance for people who, for generations, rarely traveled outside their hamlet or village.
My Maria Guiseppa Iacobucci (b. 6 Jan 1879) married Vincenzo Rossi (b. 25 Aug 1876) and they immigrated to Cincinnati Ohio in 1909.
Maria's parents were Domenico Iacobucci (abt 1850) and Filomena DiPilla (abt. 1855).
Domenico's parents were Giovanni Pietro Iacobucci (11 Dec 1814) and Maddelana Margiotta (26 Jan 1818).
I do not have Sibling information at this time. Hope this helps but it seems if we are cousins, it's back in time.
