This surname derives from a Christian name, Gaddo, short for Gherardo, used mainly in Tuscany, which was formed by syncopation and assimilation of internal phenomena (Gherardo > Gardo > Galdo > Gaddo), but since the surname is documented also in Northern Italy, the base could be also a Germanic diminutive Gado (from Gad = fellow).
The name
Gaddo (and Gaddino)
A Gado is documented in 1157 at Genoa in the "cartolare"
by the notary G. Scriba, while a Gaddo is mentioned in a document
written in Pisa in 1329: "...hereus de Gaddo de Visinyano,
... notari..." (link).
In the Confraternities' parchments kept in Siena State Archives
(link) a trace can be found of Gaddino
son of Iacopo di Rosso, mentioned on May 14th, 1331 as executor
of the will, who pays 2,433 lire of Lucca dinars to an heir (n.
546, p. 254 ) while on 7th November of the same year Azzolino
son of Gaddo Malavolti, probably from Siena, is mentioned about
a loan of 60 gold florins made to two other people (n. 548, p.
254).
In the "Cronica" of the Saint Catherine monastery
in Pisa, compiled between 1390 and 1411, several friars called
Gaddo are mentioned: "Frater Gaddus de Verchionibus"
(IV,
67), "Frater
Gaddus de comitibus de Donoratico" (IV,
84), "Frater
Gaddus, de famosis conventus nostri conversis" (VI,
129), "Frater
Gaddus de Sancto Frediano" (VI,
132), "Frater
Gaddus de Curtibus" (VII,
152) and finally
"Frater Gadduccius de Sismundis" (V,
100).
Dante in his "Divine Comedy" (Inferno, Canto
33rd, 1-90), talked about a Gaddo, a really
existed person, who was the son of the count Ugolino della Gherardesca.
Gaddo, in real life like in the book, starved to death in 1289
with his father, his brother and his nephews, all locked in the
"Muda tower" also called "hunger tower" in
Pisa.
Another renowned artist bearing this name was Gaddo di Zanobi
known as Gaddo Gaddi (12391312), who was a Florentine painter
as well as his son Taddeo Gaddi (12901366), a pupil of Giotto,
and his sons, Giovanni Gaddi, Agnolo Gaddi (13501396) and
Niccolò Gaddi.
It is anyway also possible that the surname Gaddini derives from
the name of a place: in the Diplomatic Codex of Middle Age Lombardy
in an act of May 1123 it can be read: "...predicta vinea
iacet ad locum ubi dicitur in Gaddo, est ei a mane Sancti Ambrosii..."
(link).
The Gaddinis
On a website (link) a Jacopo Gaddini can be found,
husband of Giovanna, from the Florentine family Ferrucci, who
died of plague in 1363.
According to some source the Gaddini came from Romagna, later
moved to Rome, then to Foggia (Apulia).
In ages not clearly definable Guglielmo was the prefect of Monza
and doctor at law, while Giovanni, an Aurate Knight, was ambassador
to Charles V.
In the Middle Age some Gaddini were bishops and later Guglielmo
was the Bishop of Parma and Guastalla in 1642, and in the Eighteenth
Century Giuseppe was the Bishop of Spoleto.
On the House of names website (link) a (dubious) Gaddini Coat of Arms
can be found (image).
A Tuscan
origin?
According to the Italian telephone directories of 1996, the 60%
of Gaddini dwells in Tuscany, mainly in Lucca province (53%);
15,7% are in Latium (almost all in Rome) and 14% in Liguria (almost
all in Imperia province).
On a Mormon website (link) I
found two Gaddini, both 19th century women, one of which native
of Lucca province.
From the list of the immigrants in transit between 1892 and 1924
at Ellis Island (New York), 61 Gaddini are reported, of which
42 from the commune of Capannori (26 from Massa
Macinaia, 10 from Capannori, 4 from Marlia and 2 from Badia
Cantignano) and 8 from the city of Lucca.
A map of Italy with the main cities and regions quoted in the
text can be consulted here, and my
Gaddini ancestors can be found in my genealogical tree (link).
