Johns Hopkins of Baltimore, MD is listed by name as the owner in the 1850 US Census Slave Schedule. Although only two enslaved people show up in the snip, there are actually four enumerated on the schedule --- all males, ages 45, 50, 25, and 18.

What I can't figure out is why the article doesn't mention the
1860 US Census Slave Schedule for District 2 (Bladensburgh District) which lists a Johns Hopkins as owner of 12 enslaved people --- including mostly children and babies with no easily identifiable mother enumerated among the group. I suppose it's possible that there were other people living in this part of Maryland named Johns Hopkins, but it seems like the author of the article would have mentioned the 1860 slave schedule and explained why this slave owner Johns Hopkins is not the Johns Hopkins of the University? It's possible that these enslaved people were enumerated at the Maryland Agricultural College, although that is just my hypothesis because of where they appear in the schedule.

That "2" over in the right hand column below is for the "number of slave houses" and seems to indicate that all 12 enslaved people were living in TWO houses. The male baby enumerated on line 39 is 10 months old, indicated by 10/12, and designated as Mulatto. The female baby enumerated on line 40 is 6 months old, indicated by 6/12, and designated as black. If the 16 yo female designated as mulatto is the mother of the 10 month old male baby, she is pretty young to be having babies. And who is the mother of the 6 month old female baby? There are no other women of child bearing age in the group.
