This is very difficult without a farm name. Wait... actually Fredrikstad is a city and municipality of Østfold county in Norway. Ahh, seems like Fredrikstad is also a parish in this county. https://www.wikiwand.com/en/Fredrikstad is a great website on Fredrikstad's history with sourced information too which was surprising.
Also interesting is … Østfold county didn't begin until 1918, the county before that was Smålenene county!
Oh my goodness - the library in ND has a whole bunch of Fredrikstad farm books... you may be far from there, but it's something to work with:
||Fredrikstad bys historie, v. 1
||Fredrikstad bys historie, v. 2
||Fredrikstad bys historie, v. 3
||Fredrikstad bys historie, v. 4
||Fredrikstad bys historie, v. 5
|De Figueiredo, I.
||Fredrikstad bys historie, v. 6

Glemmen farm book is found.. Glemmen wasn't separated until 1883, so if he was born in 1880 he might be in there.
Thowsen, Elsa: Glemmen bygdebok: En bygd blir til by. Utgitt av Glemmen Kommune 1962 (Your local library may have it or do an inter-library loan) I'm sure anyone can help you translate it.

Hope this helps a little.. it's a start. I actually didn't know any Norwegian, but I've taught myself a bit just regarding the family tree terminology, and of course I have a great Norwegian genealogist who can always back me up. I found a great Norwegian-English dictionary at www.rollroots.com/norwegian-english.htm. It lists abbreviation and a lot of words google translate or other dictionaries don't mention.
It's pretty likely his father's name was Jon since his last name is Johnson.
Ancestry.com is tricky, because most of them it isn't reliable. I actually relied on it and had a whole different family than the family that actually belonged to me.
