Your question "I am wondering where in Seattle a Rev. Otto R. Karlstrom might be buried?..." I don't have the answer to your question, but here is some info that might help you find it... A Rev. Otto R. Karlstorm founded the Lutheran Compass Center- a homeless mission in 1920. He was from Sweden and married to Alva. If this sounds like your person of interest, the Compass Center may be able to provide more information for you. They are still going strong in the Pioneer Square neighborhood of Seattle.
