This looks like it's the source for the info Andy posted above. He's on the top line. I had to use the tools and reduce the brightness all the way down in order to read it.

No help on "first boy" but if this is him:

Then I think this is his widow. She lived a long time after his death--dying in 1946 at age 99. She was listed at Mary C Richmond (widow Jessie) in several city directories.

It might be worth mentioning that you can't always trust info on a headstone to be accurate. Sometimes it's just an error. Sometimes people from situations such as his truly didn't know their own age. And sometimes--for reasons unknown to us--people deliberately tweak their ages. I mention this because what caught my attention is that the years in the obit, headstone, and records aren't all in agreement.
On the naval record above he's listed as age 45, which would put his birth around 1819, and about 66ish when he died. That agrees with the 45 years in slavery and dying about age 70 as stated in the obit.
The few records I saw on him (1880 census, marriage record, city directory listings of widow) mostly had his name spelled as Jessie Richmond, and mostly listed him as born about 1830-32 in Alabama, which would have put him around 56ish when he died.
The 1880 census has him at age 48/abt 1832 in Alabama, and both parents born in Alabama. Farm laborer. Can't read or write.

The marriage record in 1883 lists him as age 53, which agrees with the 1830 year of birth.
Here's the marriage record, entry #318.

I tried to find an obit for his widow to see if more info was there, but struck out.
