My parents-in-law lived in a little village with the name Segeltorp. Back then, 50 years ago, the addresses weren’t as detailed as they are today and most of the mail was addressed to the man in the house.
My father-in-law’s name is Sune and his family had the surname Paulsson and that was also the name of a close neighbour. The consequence of that was that they got each others mail. So, “our” Sune decided to change his family’s last name to Hagbjärn.
“Hag” comes from the little place Haga (just above the more known Kattvik-Båstad), and “bjärn” comes from the name of Sune’s place of birth, Hagabjär, his parent’s farm which was placed in Haga!
