A very good lesson in the importance of using the Swedish letters å/ä/ö and in not mixing modern administrative districts with old ones.
Norr Rälta is a village in Djura parish, Kopparberg county. Norr Rälta (North Rälta) was until the mid 1700's just a part of the village of Rälta, which was then divided into Söder Rälta (South Rälta) and Norr Rälta. Today, Djura parish forms part of the municipality of Leksand. However, if you write that someone in the 18th century was born in Leksand, that would mean in the parish of Leksand (since the municipality, a modern invention, didn't exist). Just to complicate matters, part of Djura records were kept in Leksand parish...but they're still Djura records. Please note that it is Rälta, not Ralta.
Bjursås is a parish to the east of Leksand parish. It isn't and never has been part of Leksand, though they are both located in Kopparberg county. Please note that it is Bjursås, not Bjursas.
Seems Margita was born 29 Oct 1771 and baptized "All Hallow's Day" (Alla Helgons dag). Unfortunately I can't make out the names of her parents other than Erik for her father - I'm rubbish at reading old handwriting. However, I can make out Norr Rälta. So, birth records Djura parish (Kopparberg county) 1765-1832, image no 16 (for AD Online; AID v129746.b16). Hopefully someone else is better able to read the names.
