What should the surnames be for the children of Ola Månsson aka August Lindbergh and his wife Ingar Jönsdotter?

Question

I am working on the Notables project. Started out with the well known Lindberghs of aviation fame and ended up all the way back in Sweden with their immigrant ancestor. I am way out of my league. Could someone please help me with the proper form for the Swedish patronym for his LNAB?

It does follow the paternal rather than maternal side, does it not?

For his legitimate children am I correct in assuming their last names at birth would have been Olsson?

Thanks in advance!
