If the missing font family was offered from either the Font Bureau or the Carter & Cone font foundaries, it is no longer available through Adobe Fonts because those two foundaries decided to pull all of their fonts from Adobe Fonts.

Note that this was not a decision made by Adobe. The two foundaries decided not to renew the contract allowing their fonts to be used. I believe Adobe sent an email to people using those fonts from those two foundaries in projects about a month ago.
