Lost Ancestor in Jamtland

I am looking for help in finding my great-grandfather's sister, Anna Olofsdotter Bylund. She was born on 28 Mar 1846 in the village of Byn in Ås parish. I know that she was in Sollefteå 1867 and is listed as moving to Hrnd (likely Härnösand). I have looked through the move-out records for Sollefteå and the move-in records for Härnösand and did not find her. Her father died in 1870 and in his estate inventory she is listed as being 24 years old and not indication of being married. She is not listed in the 1880 census. I would greatly appreciate any suggestions or help in how I might go about finding her.
Tack,
David Bylund

Any source references?

Yes, there are several. The last mention that I can find of her is in Sollefteå AI:11 (1863-1874) Bild 219 / sid 205b (AID: v122383.b219.s205b, NAD: SE/HLA/1010183).
Another reference is Ås AI:6 (1857-1864) Bild 90 / sid 3 (AID: v115478.b90.s3, NAD: SE/ÖLA/11105)

I notice the brother Erik is a mormon in America [Ås AI:6 p 3]. When did Anna get the name Bylund?

I lost track of the mother, Agneta Olofsdotter (b. 1807). Where did she go? I notice that sister Britta also went to America (1871). Maybe Anna ended up there too if the mother was dead ...
