Folke Isaksson was born on October 9, 1927, Kalix, Norrbottens Lan, Sweden. He was a missionary and Lutheran preacher's son of Otto and a hospital nurse Hilder (Nordqvist) Isaksson. He was the older brother of Olov Isaksson and grew up in Kalix and in Gammelstad in Luleå. In 1937, when Folke Isaksson was 10 years old, the family moved to Gammelstad. The boys Folke and Olov felt that they were being banished to Gammelstad. It was a very different society, at the same time both rural and with a great sense of church. For the first two years, the family lived in the center of Gammelstad with a very tough elderly lady and her unmarried daughter. They had a small farm and the cows were roaming and the screams at pig slaughter the boys Isaksson experienced very close up. Then the Isaksson family built a house opposite the present Assembly House in Gammelstad.
