I know you may have the below background and only acts for death and burial information, I had to do the background to FULLY identify these two people to verify information so that I don't find the wrong ones. I also found this person "might" be the same person as for whom the town of Kelly, Wyoming was named. You may already have known that.
The image of the 1910 Census for Grovont, Uinta County, Wyoming, enumerated 6 May. (NOTE: GROVONT, Wyoming)
Additional information helpful to the search:
William J had indicated second marriage, Sophie first marriage, number of years married indicated by boh was "0". The record in the database of Brigham Young University "might" be wrong. It could be a typo, misread of "0" into an "8". As evidenced by the date of death on the same source, which indicated "1943", when evidence shows her date of death was "1933".
This couple is listed twice in the 1920 Census, both images reviewed.
1920 Census for Victor, Teton County, ID, owned the property.
Willam J. Kelley, 52, born in Iowa to father born in Indiana, mother in Vermont, Farmer.
Sophia S, 57, born in Wisconsin to both parents born in Germany
Louis Erickson, born in Utah. hired hand, 31.
--Census enumerated on 20 January.
1920 Census for Election District 15, Lincoln County, Wyoming, owned the property.
William J. Kelly, age 53, born in Iowa to father born in Indiana, mother in Vermont, no employment.
Sophie(or Sophia, handwriting difficult to prove either) S, age 57, born in Wisconsin to both parents born in Germany.
--Census enumerated on 13 May.
With the above, the 1900 Census for Antelope, Kimball Co, Nebraska
William Kelly, born January 1867, 33, Single, born in Iowa to father born in Indiana and mother in Vermont. Cattle Dealer. (NOTE: CATTLE DEALER).
The 1880 Census for Center, Cedar County, Iowa.
James Kelly 30, born Indiana
Laura, 28, born Vermont
John W, 3, born Iowa
George 1, IA.
--All census appear to agree John born in IA, to father born in Indiana and mother in Vermont. It also appears to confirm his parents were James and Laura.
The Idaho Death Index 1911-1951 on Ancestry.com.
Sophia Silwood Kelly, died 4 Dec 1933 in Driggs, born 6 June 1863, certificate # 085440
--This date is different than the one you have. I also found a version of the death listing on the BYU site, it showed 04/12/1933. Note, the dates are reversible, 4/12 or 12/4. The listed date on one of the databases is not accurate, the actual death certificate would have the actual date. I NEVER trust database entries.
--As you can see, the other "researcher" had her born in 1883.
Now, if you haven't before, (I suspect you already have), look at the locations of Driggs, Victor, in Idaho; and Jackson Hole, and Lincoln County in Wyoming. They are all in Teton County, either Idaho or Wyoming, and very close. So, you might also want to post in Teton County, Wyoming.

Now, as far as his farm land. Go to: http://www.glorecords.blm.gov/
Click on Search Land Patents.
Enter State of Wyoming, last name Kelly, first name William, Search
There are five listed, three are William J, of which two are in Teton County. Click on the first Teton County listing, for 1913.
You can see he obtained 40 Acres. Click on the tab for Legal Land Description. Note: Township 42-North, Range 115-West, Section 10, NENE quarter. In the 6th PM (6th Principal Meridian)
--In the other purchase, it was in the same area, parts, SWNW, SENW and SWNE.
Go to: http://www.esg.montana.edu/gl/trs-data.html
Enter the above land locations.
In the next window, you'll see locations. Click on "Switch to TerraServer".
In the next window, Click on the largest block for Size, and switch from Aerial Photo to Topo Map. SAVE THIS WINDOW as you just read the below. You can go to the sites below later.
Now, in the new window, you will see Kelly, Wyoming. Finding a William J. Kelly purchasing land in that area was somewhat startling. Then, I found:http://www.free-press.biz/Jackson-Hole-WY/Kelly-Wyoming.html
The town name was originally Grovont (the name of the town where William Kelly lived in the 1910 Census). This site says the name of the town was changed to honor billy Kelly, a local sawmill owner and farmer.
Also see footnote 1, which leads to pictures about the slide and also names the town, named after William J. Kelly.
Also: The 1900 Census identifies William J. Kelly as a Cattle Dealer, this site: http://www.nps.gov/history/history/online_books/grte2/hrs9b....
Shows: "His neighbor, William J. Kelly, established a cattle ranch, but made his living as a cattle broker, buying and selling cattle for export."
NOTE: WHILE THIS IS VERY INTERESTING, THERE IS NO PROOF THIS IS THE SAME WILLIAM J. KELLY AS THE ONE YOU SEEK. You MUST look for more information to confirm or eliminate this connection.
Now then, back to the topomap.
In this window, you'll see it is divided into red squares, they are the sections.
Now where you see the word "Kelly", move down into the red square just below the name, and then one to the left, now left click in that square. Now, in the next window again left click in that square.
Now, you'll see a red square having the number 10 inside. This is Section 10. In his land purchases, he obtained land in section 10, in the NENE quarter, SWNW, SENW and SWNE.
So, look at this red square of Section 10. Divide it into quarters (half vertically and half horizontally). In the top right corner divide it also into quarters. The NENE purchase would be in the top right corner. The SWNW, divide the section into quarters, then in the bottom left corner divide it into quarters. This land would be in the top left side of that area. You can then figure out how to do the other two. In his two purchases, he had 160 acres, all in 40 acres each.
For further information on this person, I'd look at Teton County. Contact the town of Kelly.
