"Cosimo I of Tuscany."
"looks like that line is now defunct"
Anon can assure you that at least the Cosimo line is not defunct, it branched off imto some very important surnames from OTHO Gerard and family.
Cosimo Gherardini
Otho Gerard/Gerald (fitgerald)
Transliterations…
Gherardini - Gerard - became new world Jarratt
Also included is some people like Father John Gerard, who was implicated in the Gunpowder Plot but fled to the Vatican and his family, who are still nobles in Britain.
The New World line of Gerards (Jarratts) was said to have died off but luckily county files from VA were preserved during the Civil War fires, and they say otherwise.
