Johanna worked at an inn in Torbjörntorp north of Falköping at the end of the 1860s. I am pretty sure that’s where she met Karl Adolf’s father, whoever he was.
The owner of the Inn was Adolf Ruckman. The son of a minister who’d been forced to resign for drunkenness, Adolf started out as a bookbinder, became a singer and an actor, and then an inn keeper. His sister and her husband owned Viken, the property outside of Falköping where Johanna and her family lived when she was young.
I have no idea what kind of relationship Johanna had with the Ruckman family. But she did name two of her children after two of the ten Ruckman kids: My grandfather, Karl Adolf, and his younger sister Elma Georgina.
