Henry W. Nelson, born WI 1882 - died in Oregon?

Dear Listers! Henry William Nelson, born in Vernon Co., WI Feb. 14, 1882 (WW1 draft says 1881!), was the son av Hans Nelson (1842-1911) and his 2nd wife Jane L. Clark (1862-1937). Henry married in Viroqua, WI Oct. 15, 1913 to the widow Charlotte Jeannette aka Lottie nee Chalk, born Aug. 4, 1871 - the daughter of John and Hannah Chalk. Lottie's birth place varies between MN, IA and WI and is thus a big «mystery». She was first married to Harrison Raymond Abbey from Vernon Co., WI. In 1913 Henry and Lottie moved to Portland, Multnomah Co., OR where Lottie died May 24, 1956. However, she was divorced from Henry some time in the mid-1920's, and Henry supposedly moved in with his halfsister Della May Kellar (1879-1937) at Fern Hill, Columbia Co., OR and is thought to have died there. Both his sister and his mother died in 1937, and Henry died BEFORE them, but when and where? An additional note: His mother Jane was known during prohibition as the biggest «boot layer» in Columbia Co., OR! She smoked a pipe and wore whiskers! Quite a lady! So we have two challenges here: * Exact place of birth of Charlotte Jeanette «Lottie» CHALK? * Exact date and place of death of Henry William NELSON? Thanks a million in advance for any assistance you can give me in this matter! Very sincerely yours,
