Lyncoya Jackson (c. 1811 – July 1, 1828) was the second adopted son of American President Andrew Jackson and his wife Rachel Jackson.
 Born to Creek (Muscogee/Red Stick) parents, he was orphaned during the Creek War following the Battle of Tallushatchee.
 Lyncoya was brought to the Jackson home, The Hermitage, in 1813.
 Lyncoya was brought to Jackson after the surviving women in the village refused to care for him.
 Jackson took pity on the orphan, writing that he felt an "unusual sympathy" for the child, perhaps because of Jackson's own past as an orphan.
 Lyncoya was educated along with Andrew Jackson's first adopted son, Andrew Jackson Jr., and Jackson even had aspirations to send him to the American military academy, West Point, but this proved impossible.
 Instead, Lyncoya was apprenticed to be a saddle maker until he died of tuberculosis in 1828.

 The park was listed in the National Register of Historic Places on 1997.

The Special Law of Curvilinear Disparity is a theory, put forward by the political scientist John D. May, which posits that the rank and file members of a political party tend to be more ideological than both the leadership of that party and its voters.
 May contends that politically active people can be classified into three major strata or echelons according to their relative status within a party.
 Members of these divergent strata have contrasting motivations for being politically active and calibrate their ideological stances to differing extents as a result.
