No obits as newspapers of the time were small -- only 8-12 pages and there were so many killed. Funerals would have taken place immediately upon recovery of bodies, as well. Word spread fast in this small community where everybody knew everybody. There were articles on what had happened, including lists of those lost.
Using the Wyoming Newspaper Project (Google it) is an excellent suggestion for you, as well as anyone with interests in this area. For instance, the surname Wagstaff is not all that common around Evanston/Almy, I recall. Clicking on the county search, choosing Uinta, and entering just "Wagstaff" in the search box brings up 63 entries from 1896 and well into the 1900s, One I looked at randomly was an item on a wedding. For common surnames, use whole names in the search box, in quotes. Also, check adjacent Lincoln and Sweetwater Counties, as miners often had miner sons, or daughters who married miners, and who had moved on.
