The recipient is presumably William King (1768-1852), who was a member of the Massachusetts Senate in 1807-11, and the first Governor of Maine in 1820-21.
Gov. King is not named in the salutation, or anywhere else in this four-page document; it is possible that the recipient was Adj. Gen. Samuel Cony, named at the bottom of the second page.
The sender is apparently Joel Wellington (1782-1865). He was born in Massachusetts, and trained as a surveyor. He served in the Maine militia, was a member of the Maine constitutional convention in 1819, and sat in the legislature representing Albion. He was also a selectman and the first Albion Postmaster from 1825 to 1831. He was commissioned to design the capitol park in Augusta in 1827.
Samuel Cony (1811-1870), was born in Augusta, and was a graduate of Brown University in 1829. He became Maine’s first Adjutant General and Quartermaster at Maine’s transition to statehood in 1820. He was the 31st Governor of Maine in 1864-67.
