I spent months reading the documents submitted to Havana Province’s Registry of Associations available at the Archivo Nacional de Cuba. The Registry ran from 1881 until 1976, and organisations (religious or otherwise) that met regularly were supposed to submit paperwork to the government. This mostly meant that organisations run by men were supposed to do this. But, sometimes, women emerge in interesting leadership roles in the Registry.
The printed version of Cabildo Africano Lucumí’s documentation from 1901 is available through a few United States libraries. I will note that a colleague found this document from 1910 for me at the National Archives and photographed it for me, and when I went back to look for it, I never found it cited in the catalogues there. I wonder if there are other pages. It looks like there should be.
