All my info comes from my Aunt Phyllis who is Minnies daughter. Phyllis thought that Minnie and Susan knew where he was but would not say. No further contact was made apparently.
In doing further searching I did discover that Harlan did die on May 1, 1956 of a cerebral hemmorage at age 63. His wife Icie Eastman whom he married in 1947 gave the info for the death record. Minnie had 3 children , my father Harlan Truman, Phyllis and Paul Jr, (who passed away at I think 14.)MY dad is 80 and Phyllis is 86. She has a lot of info and pics. I will get some photos and pick her brain some more. By the way we have good genes for living a long healthy life. No cancer as far as I Know in any of my relatives.
