Okay...
In The Lord of the Rings, from the day that Frodo moved out of Bag End until he set sail at the Grey Havens (about three years), there were seven people who claimed by hereditary title, by election, by substitution, or exercised by force the leadership/governance of The Shire or regions of The Shire. I would like you to name all seven and give at least one title (relating to their relationship to The Shire, whether it is official or not) for each of them. You do not need to provide quotes. All information is available straight from the narrative, but is probably also found in the appendices. I hope you enjoy thinking about it.
For example, in the same period, Gondor had...
Denethor, Steward
Imrahil, Prince of Dol Amroth
Forlong, Lord of Lossarnach
Angbor, Lord of Lamedon
Faramir, Steward
Elessar, King
Faramir, Prince of Ithilien
...there may be one or two lords that escape my memory...
