I looked at your family tree, and saw that there is a birth certificate of Domenico Antonio, baptized as Domenicantonio. The surname is IACOBUCCi. He is the son of Sebastiano and Vincenza Margiotta. Born in Pratola, L'Aquila, IT on 11 March 1852.
This birth certificate picture is dissonant with the rest of the information.
Even 3 wives and a slew of children, and the surname becomes Iacobacci .. I'm afraid it's easy for the reader to get confused and also I can't explain the much younger one you are looking for. Frankly, even if you want to help it is really difficult, if you don't start from firm and well-documented points. So which is your Domenico Iacobacci / Iacobucci, the one born in 1852 in pratola, or the one born in 1848, no one knows where, or a third born ... son of a Giuseppe, and who was born in 1865 Giuseppe or the son??
