Bi here from post nr 2. I´m sorry that the beginning of my post didn´t show. I should have started: Oskar Valfrid was still in Sweden 1900, according to CD Swedish Census 1900. Sorry about that.
The girl; Karolina, born 1893 is a noted as a dotterdotter (daughter's daughter). Seeing Bo´s attachment it looks like Jenny´s daughter. Maybe Jenny is dead or has left by 1900.
