1) Landet might mean Alingsås Landsförsamling, that is this parish. But the son August has in Loco (in this place), Erik Anderson has L (in Loco or Landet?), some of the others have Do (ditto), and some have a mysterious ?___l.
2) There is indeed a marriage date 17 Aug 1872, but who has he married? He moved 1873 to page 384 (GID 1878.24.31700), without any sign of a wife. And from there to America 1881(?).
Perhaps the marriage date is an error, note that he came from G.B. (previous volums) page 339, and he is in Alingsås Lands HFL AI:10 1860-1873 page 339 (GID 1878.23.62000) without any wife, he came from Lena 13 Nov 1872.
On GID 778.25.32000 (Lena parish) he came from Alingsås 3 Nov 1871 as no 55, and left for Alingsås Lands 28 Oct 1872 as no 47. No sign of marriage or wife.
3) The date 25 Jan 1871 is in the widowed column, so check the death records for that date (in _SCB Älvsborg).
On GID 1878.23.6000 (should be 1878.23.60000) there is a date in the death column for Anna Maja Jonsdotter, and she is crossed out.
