I also belong to ancestry, but when it comes to swedish research, you do need Genline.
I use to belong to Genline yearly, but now I use it only for one month at a time. I currently have a subscription until August 21st so I can access and see what I can find for you. It took me a couple of years to get a fine grasp of it and can read it pretty good as long as the writing is legible. I will be out tonight, but before work tomorrow, I will go to Tastarp, Ganarp, Sweden and see what records they have and how far back they go. You can actually go to genline.com and see for yourself what records are available. I am almost ready to leave here for the day.
Hopefully I find something for you. I copied your information in a word doc so I can work from it.
My history, my grandfather Ernst Rosell came from Ballefors, Skaraborg, Sweden. Rossell is my maiden name.
