On 13 April 1910, a Arthur David Doner married Rose Ellen Kernahan. The ceremony took place at the Church of the Redeemer, Watertown, NY. First son Harry James Doner born and died on 15 June 1911. Second son Clifford Arthur Doner (my father) was born on 29 Apr 1914 in Watertown, NY. Arthur was born on 11 Dec 99; Rose was born on 17 Dec 1886. In the late 1920's-early 30's, Clifford and Rose moved to Livingston, Montana (with the possibility of some layover time in St. Paul, Minnesota); Rose subsequently married Raymond E. Koons. I have no knowledge how/why the marriage ended. The Kernahans were in the Watertown area with roots in Ottowa, Onterio/Hull, Quebec. I am responding because of the similarity in the name you are researching. Garry.koons@hqasc.army.mil
