I am endlessly fascinated by people who name their children after public figures, especially when those names reveal a particular political or religious commitment.
In the case of William and Rachel Smith of Wrentham, Massachusetts, that commitment was the abolition of slavery. Of their (at least) twelve children, three are sons named Frederick Douglass (b. 1851), John Brown (b. 1862), and Abraham Lincoln (b. 1866).
The Smiths, one of the few black families living in a rural town near the Rhode Island border, owned a modest farm worth $350 in 1870 (their white neighbors' farms were generally worth $700–$2,000). Both William and Rachel were born free in Massachusetts in the 1820s.
