Swedes used patronymics and most didn't have a fixed "family name" until later than your Johanna. The name law was in 1901, if I recall correctly. That name law said to have a permanent family last name. Swedes had been gradually changing their customs before them, and those changes were earlier in the cities, but most likely your Johanna didn't use the last name of her own father. (These patronymic last names are literal. Larsson literally means son of Lars. Olsson literally means son of Olof or Ola, etc.
The child of a Lars something would be Larsson (male) or Larsdotter (female). Youhave the right record (as far as her name goes). Did you previously have that information that she was born in Johnstorp parish? It is possible someone with this very common name could have been born elsewhere in Sweden with the very same birthdate.
Read this interesting and informative article about Swedish naming customs. You must understand the customs or you will end up researching the wrong lines.
Jonstorp is a församling (parish) in the former Malmöhus county, Skåne province. (Malmöhus and Kristianstad counties were combined in recent times to become the new Skåne county.)
Try not to write the birthdate as 6-4-1868. We in the U.S. would interpret the date as June 4, 1868. Most Europeans (including Swedes) would interpret the date as April 6, 1868. Write out the month to avoid confusion.
Did she emigrate? If so, when and where?
I am not related, but I have access to various Swedish databases and other Swedish sources.
