Considering where they got their money from I don't think they should be commemorated. As I say elsewhere in this thread, the DeWolfs already took their own names off of some of their properties because it was sullied after their fortunes soured in the 19th century, including their most prominent holding in Linden Mansion (formerly DeWolf Mansion). Slapping their name on a structure is in essence commemorating their historic footprint. It's irresponsible to slap somebody's name on something to effectively celebrate their legacy without interrogating what that legacy really was. Brown University has been dealing with the same thing.

Its up to the descendants of these families how they want to handle it, but if they want to celebrate their ancestry they should do so aware of the fact that their historical importance was heavily funded by Cuban sugar plantations and West African slaving ships. I'm sure they're good people and would be receptive to considering that. It's a shitty thing to reckon with so I'm sympathetic.
