With thanks to Marion for citing one of the records you have been looking at: FamilySearch, by just naming the collection 1880-1930 is not really doing a very good job of showing when the information was gathered.
I see there are several volumes available where Pehr Frederik appears.
By skipping back to page 1 I was able to see that the volume cited by Marion covered 1900-1910. That's one way.
The info at FamilySearch says Event Place: Snavlunda, Örebro, Sverige. You can look up the parish Snavlunda at Riksarkivet - here is a link to their list of volumes.
There is also volume info at FamilySearch, Volume: AIIa 1
In the notation of Riksarkivet this is SE/ULA/11361/A II a/1
Riksarkivet shows the years covered by a volume in their list.
