Lydia Gardiner Faxon (1832-1850), Adeline's older sister. She had just died in June of consumption at the age of 18.
The Chapman Brothers
Robert Boyle Chapman (1837-1894) and Charles Henry Chapman (1840-1917) were sons of Avis Waterman Lockwood, sister of Amos Lockwood. Amos Lockwood married Sarah Deming, sister of Adeline's mother.
Jerome Bonaparte Kimball
Jerome Bonaparte Kimball (1832-1909). Originally also from Slatersville, he was a few years older than Adeline and presumably a relative. That connection is currently unidentified. He attended Harvard College which likely explains his sighting at a Boston concert attended by Adeline (See See page 24). He became a lawyer and was Attorney General for Rhode Island.
The Game of Button
"Button, button, who's got the button" per Wikipedia:
Button, button, who's got the button is a game of ingenuity where players form a circle with their hands out, palms together. One child, called the leader or 'it', takes an object such as a button and goes around the circle, with their hands in everybody else's hands one by one. In one person's hands they drop the button, though they continue to put their hands in the others' so that no one knows where the button is except for the giver and receiver.
The leader, or all the children in the circle, says "Button, button, who's got the button?" and then each child in the circle guesses. The child guessing replies with their choice, e.g. "Billy has the button!"
Once the child with the button is finally guessed, that child is the one to distribute the button and start a new round.
