Perersen Sweden

after fruitless searching for my g grandmother ,I finally have a copy of her birth certicate from karl johan parish swedn . her father is shown as - - olaf Petersen . I can,t decipher the first 2 words, very curly writing.she was illegitimate which was no surprise. can,t quite decipher her mother,s last name.. very frustrating.. many thanks to the 2 people in Sweden who helped me, they couldn,t deciher the words either. anne
