On October 1, 1845, a baby girl was born in Texas to German immigrants Joseph and Elizabeth Beitel.
They named her Annexation.
(At right, she’s listed on the 1850 Census between her brothers Henry, 7, and Rodolph, 2.)
Why the name “Annexation”?
My guess is the name was inspired by the annexation of the Republic of Texas, which was finalized by President James K. Polk on December 29, 1845. Texas became the 28th state admitted to the Union.
Annexation Beitel seemed to prefer the nicknames “Anna” and “Annie” during her lifetime, as this is how she’s listed in most other places.
