Hi Britt-Maria,
I have found the names of her parents in the Swedish church books on Genline.
Her father's name was Olof Svensson born 1793-02-28 in Tegneby, and her mother was Helena Andersdotter born 1793-03-23 in Tegneby.
The family can be found in the HFL 1841-1848, AI:1, Leby, Tegneby and on Genline at GID: 955.1001.45900, page 77.
And the again in the following HFL 1848-1856, AI:2, GID: 955.1002.59900, page 81.
Hope this helps!
Have a nice day!
Don
