@futurist The issue with this is that the matches in those school census records don't name a "Park", but rather other children's names. And in 1894, the only 11-year old Herd recorded is a female.

I'm intrigued. What's the name of the 9-year-old in the 1892 census?

As for the F (female) sex in the 1894 Mississippi school census for Herd, that might simply be a typo. Really, what one should do is to see if the siblings' names match, as well as the father's name. I personally have not seen either the 1892 or 1894 entry, so I can only comment on them based on what others have told me about them.

Charles Edward Graves's (1888-1999) Gerontology Wiki page contains some old articles for him:

He is likewise validated by the GRG but not by LQ, yet, at least. I think that the GRG validated him based on his 1896 Mississippi school census entry, which is slightly ambiguous (it mistakenly lists his younger brother Warren's name as Ed but gets his name and all of his other siblings' names correct, and lists his own age as 17 rather than 7 but gets all of the other ages correct) but still good enough, especially when it is combined with his family's 1892 Mississippi school census entry (on which he himself is not listed, which he would have been had he genuinely been 17 instead of 7 years old in 1896).

LQ has discovered a photograph for Sai Kitamura (JPN, 1893-2003). It's rare to find pictures for long deceased Japanese SCs, so I am thrilled! 😀
