W. E. B. Du Bois
William Du Bois claimed Elizabeth Freeman as his relative; he wrote that she had married his great-grandfather Jack Burghardt. But Freeman was 20 years older than Burghardt, and no record of such a marriage has been found. It may have been Freeman's daughter, Betsy Humphrey, who married Burghardt after her first husband, Jonah Humphrey, left the area "around 1811", and after Burghardt's first wife died (c. 1810). If so, Freeman would have been William Du Bois's step-great-great-grandmother. Anecdotal evidence supports Humphrey's marrying Burghardt; a close relationship of some form is likely.
