Welcome to Rootchat, Mixy
I had a similar case for a 71yr old, described as Boarder, he was living with the family of a younger cousin (as Head)(I had already the connection from a descendant).
What was interesting, is that his wife is also in the same house,but in a differant room, as Head. As the husband died that year, and the wife , the next I can only think that she was not fit enough to care for him.
Only a guess but seems to make sense
