Thanks for the follow up. I have mined the Adams County records pretty thoroughly over the past 15 years, including the courthouse holdings, Eastern Washington state archives, Lind's historical society (in the basement of the old theater). Ritzville's library and also been in contact in the past with some of the locals, including historians and genealogists. I've never come across any other records for Wesley Walsh but he also was not my primary focus until recently, taking this approach to hopefully find out more about my Great-grandfather, Charles Marshall, Wesley's neighboring homesteader and business partner for a brief time. I need to revisit the land sale records at the courthouse to see what they might have. I did find his homestead records (online US BLM land patent records).

BTW, an info update: I now know that Viola Sweetser married "George" Walsh on August 15, 1898 at Prescott, WA. Viola Sweetser Walsh died 11 AUG 1922 in St. Mary's Hospital in Walla Walla, a resident of Prescott and was a local school teacher. Her son Verner Walsh died 19 May 1907 (he died as a small child, barely 4 years). Viola was divorced from her husband, George Walsh, who then died in a logging accident near Leavenworth, Washington in 1904 (his death is now narrowed down to at least the year). Considering that Viola had Verner in 1902, it seems this divorce must have taken place between then (probably in Walla Walla County) and 1904 when he died. To be safe, let's say they divorced between 1900 when oldest son Charles was born and 1904 when George was killed in that logging accident. The strange thing about this though is that Viola's only daughter, Josephine, was supposedly born in 1904 or 1905.

As you can see, it's all quite a strange series of events, quite a mystery. I gladly welcome any and all hunches you might have to offer. The fact that Viola, as it now appears, divorced Wesley before he left the Prescott (and/or maybe Hatton) area to work in the timber industry around Leavenworth where he died in 1904, adds a little more detail (I unfortunately don't have an exact death date or place or burial).
