The modern Democratic Party wasn't formed until 1828, or 19 years after Meriwether's death by suicide. However, that party had historic roots back to 1792.
While the main parties then were "Democratic-Republican" and "Federalist", President Thomas Jefferson was of the "Democratic-Republican" party.
The modern Democratic Party came by a split of the "Democratic-Republican" party, and those who called themselves the Democrats were adhereing to Jeffersonian principles.
