How the name RUDENIUS was born. Until early 1900 it was common to make the last name after the fathers first name. And the eldest son got the same first name as his grandfather.
Like Peter Johansson – son Johan Petersson – sonson Peter Johansson – ….. the sonson’s brother could be Anders Johansson and sister Anna Johansson.
My father was born 1910 and this habit broke – he got the same last name as his father – Pettersson. At this time many Swedish had names that ended with –son.
My grandfather was born in a farm/property with the name RUDEBO. My grandfather’s elder brother changed Pettersson to Rudenius after Rudebo.
About 1940 my father and his six brothers also changed from Pettersson to RUDENIUS. My grandfather was dead at this time and my grandmother never wanted to change her married name.
So I and my cousines are born RUDENIUS after RUDEBO as the last name. I kept Rudenius after I married.
This is RUDEBO, Linneryd, Småland, Sweden.
