I found the Davidson Family Tree, http://trees.ancestry.com/tree/25636972/person/1684739683
which contains info about Mary Jane Davidson. It says that she married William Edward Hammond (no birth or death info provided).
In 1870 Mary Jane was living with her family in Payette Valley, Boise, Idaho Territory.
Wm G. Davidson, b. KY, 31, farmer.
Sarah J., b. OR, 18, keeping house.
Wm Arthur, b. ID, 3.
Mary Jane, b. ID, 2.
In 1880 the family was living in Ada Co., ID. Two more children were added; Alfred & James.
I searched Ancestry, Familysearch and Western State Marriage Index but didn't find the marriage record. Idaho didn't require marriage records on a state level until 1947. Mary might have married William between 1880 and before 1911 when she died in Lethbridge, Alberta, Canada.
I couldn't verify her death info either.
You can post on the Alberta, Canada Message Board on how to verify her death.
A William Hammond b. abt. 1867 in Utah Territory was found on the Young Family Tree, http://trees.ancestry.com/tree/19890472/person/1694404127

The rest of the folks living in their house were boarders.

I think Lillian was living at home while her divorce was in process.
In 1921 Lillian married Mr. Craner.
In 1930 Lillian, her husband and son were living in Missoula, Missoula, Montana.
Dewey M. Craner, b. ID, 31, warehouse foreman sugar factory.
Lilliam M. Craner, b. ID, 34.

I think the above Edward was actually Edward W. Hammond b. abt. 1916.
Lillian Craner died 14 July 1934, Shelley, Bingham Co., Idaho. Source: Davidson Family Tree.
I couldn't verify this fact, however, if you find her obituary that's verification. There is an obituary volunteer in Bingham Co. at http://freepages.genealogy.rootsweb.ancestry.com/~obitl/voli...
Scroll down to Bingham Co. and choose Renee.

I couldn't verify this info because Idaho doesn't release death info until 50 years after the event. There is an obituary volunteer for Bannock Co. at the same web site mentioned above.
I hope finding the obituaries will help you fill in more blanks.
The first William Edward Hammond was very elusive and moved around a lot. People who moved frequently are the hardest to find. Successful Searching!
The Family Tree shows he married Florence Idona Luman but I don't think so. I couldn't find their marriage info.
Comment: Groom sometimes known as William E. Davidson.
