I am sorry, I do not know who Elsa Jönsson is.
What I mean is that Elsa was the one who told they other persons about all the things and money which Hanna had when she died. Elsa was said to have helpt Hanna on her last time in life.
There were two more children in Nils and Hannas marriage, but they died as small children some years before Per and Jöns were born.
