Don.
Anybody would have difficulty reading that terrible handwriting.
The person on line 16 (who I suppose is your candidate,) is
P. Albertina Math. Carlsson She comes in to Torsåker from Trosa in 1886, and moves on to Sättersta in 1887. There, she can be found, more readable, in AI:18, page 86, line 25 (GID 808.5.50900). Her date of birth is Dec. 15, 1864.
On top of page: Solberga ½ mant. Frälse. ½ Mantal tells something about the size of the farm for taxation purposes. Frälse says, this farm is owned by a larger estate, owned (or rather: at some time in history, owned) by a nobleman, and thus free from taxation. Simple, huh?
I suppose, you are aware, there are two parishes in Sweden by the name Torsåker, and that you have evidence, that the one in Södermanland is the correct one.
Best wishes in your search,
Per Thorsell.
