I added several categories to his profile and sources related to his Obituary and Grave information. I also noted that while he never married, he did have 2 illegitimate children - only 1 of which was formally acknowledged (due to a Swedish court case - otherwise it's possible neither would have been acknowledged). I'm not sure how much information can be found on these two children to add them to the tree, but if someone wants to pursue it, I've given at least a few tips on them.
