Vital/service/immigration details are obituary-reported, not yet confirmed with civil or military records. Obituary names Lara among grandchildren, but does not specify her individual parent; no parent edge inferred. Parents of Adolf remain unknown. Military follow-up — October 3, 2026: Re-read the original Chicago Tribune obituary; it explicitly identifies United States Army service. Searches under Adolf Trenkenschu and surname variants did not produce an independently identity-matched military file. VA memorial search returned a different Peter M. Trenkenschuh, not Adolf; no record was merged. Dates, unit, final rank, theater and awards remain unknown. No Vietnam service is inferred from age or immigration year. Next target is an Army personnel/separation record using the full name, January 9, 1938 birth and August 19, 2019 death, with obituary attached for identification; appropriate access depends on actual separation date.
