From the 1920 Census I have that this family was in Wyoming but were listed under Bringle:

Moss M. Pringle - age 36 (1884) b. Wva. - Dairyman, farm dairy - (owns home)
Nancy O. Pringle - age 46 - (1874) b. wva. - farm labor - home farm
Laina - daughter - age 11 - b. Wyo
Oscar - son - age 8 - b. wyo

Moss and Nancy had a daughter born in Lewis County WV March 28, 1914. Believe she may have died in Wyoming and is buried there as I found this:

Catherine Pringle - died 4-25-1916 born 01-01-1914 - age 2 - Mt. Pisgah Cemetery Gillette Campbell Co., Wyo.

I believe the children Oscar and Lena/Laina ended up in Scio, OH. The obituary for Moss Monroe stated that Oscar and Lena were adopted. I wondered if there was any way I could find maybe an obituary or death record for Catherine and find if an adoption record existed in Gillette for Oscar and Lena. Nancy may have died between 1920 and 1930 but I do not know where this might have occurred. If Moss owned land, land transaction during the time period might give a clue as to when he left Wyoming.

Any thoughts or guidance would be greatly appreciated.

Do a Land Patent search at this site http://www.glorecords.blm.gov/
and Select the state Wyoming and type in Pringle as the Last name and press Search. You will get a list of names including Moss Pringle indicating Homestead property. If you click on his name and then look through the different tabs you will get further information. Depending on how familiar you are with Legal Land Descriptions, for example, you can actually located the property on a map. Usually the Town Hall, in this case in Gillette, has a big map and can locate the property using the information available. If you call them they may or may not help you, though, or they may suggest a resource.

Thank you very much for your help. I found the land document.
