  General Notes:

https://en.wikipedia.org/wiki/Gherardini_family
... The first exodus took place around 1120 with the death of Matilda of Tuscany.
One of the heads of the family, Gherardino, and his children (Tommaso, Gherardo and Maurizio) decided to leave Tuscany. Initially they were members of the retinue of Louis VII of France, called the Young, and then they were with Henry II of England and went to conquer Ireland, where, according to tradition, they started the FitzGerald dynasty. This issue is still being studied by some historians

Story of the family:
https://www.geraldini.com/documenti/before-america/Before-America-Part-1.pdf
The first ancestor to immigrate to England was Otho Geraldini. Otho was from Tuscany (now
Italy) and he was a Duke. His move was made in two steps -- first to Normandy in the first
quarter of the 11th Century and then to England in 1041 AD. So from Otho (Geraldini) we have
a progression of names such as: Walter FitzOtho, Gerald FitzWalter, William FitzGerald, and
William FitzWilliam. Two prominent branches were the FitzGeralds and the Geralds. The
FitzGeralds branch of the family went to Ireland. The Geralds became Garrard, Garrett, etc.
Otho was from Italy, born around 1006 AD. He was a Florentine and a member of the Geraldini
family. Sometime between 1016 and 1035 Otho went from Tuscany to Normandy (France) in the
caravan of the Anglo-Saxon King Canut (Cnut or Canute) who had passed through Florence on
his way home from a pilgrimage to Rome. Later, Otho came to England with Edward the
Confessor when Edward was called back from exile to be King of England in 1041.
Otho Geraldini, Duke of Tuscany, came from a family whose beginnings, so say the legends, go back to the days of Troy. Definite records take us back well over a thousand years, and say that the family was indigenous to Italy, being either Etruscan or Roman. Its members had estates in various parts of the Florentine territory. In Florence, their principal residence was near the Ponte Vecchio Bridge. Their tower still exists, being part of the Palazzo Bartolomei. The Italian historian Gammurini, says "the Gherardinis were among the most ancient and wealthy families of Tuscany in 900 A.D.
The Duke of Tuscany's father was Baron Ottorus Gherardo GHERADINI. His father was
Lord Otterus (Othoer) Gherardini. His father was Mathias Gherardini. His father was
Cosimo (Cosmus) Gherardini who was born around 870 and was the 1st Great Duke of
Tuscany.

Otho married.
