Mrs May Wright Sewall was being worked on. When you read the Wikipedia article, it becomes all too obvious how notable she was. She founded multiple organisations and was known for her suffragist ideas.
The article introduces these organisatons and consequently to indicate the relations, new items have to be created in Wikidata. I only did two and I added her husbands, men that supported her in her undertakings.
By adding these new organisations, it becomes possible to link more people to them. They thereby gain notability and it becomes more likely that at some stage they will get their article as well. The least new people and organisations added in Wikidata do is complete the tapestry of information of an age gone by.
