I am not a family member, I just did a quick search for this family. This is what I came up with.

McGuire, Mary W, head, f, w, 72, widow, MO, MO, IN
Williams, Eliza, sister, f, w, 66, single, MO, MO, IN
Hilton, Square W, son-in-law, m, w, 37, married, VA, WV, VA
Hilton, Rena, daughter, f, w, 36, married, MO, MO, MO
Road, Rena, grand-daughter, f, w, 16, single, CO, KY, MO
------------------------------------------------------------
1930 Cripple Creek, Teller County, CO Census

Hilton, Rena, wife, f, w, 46, 1st m @ 19, NE, Scot, MO

Colorado Marriages 1858-1939, an index compiled by the Denver Public Library, c2004 Colorado Genealogical Society.
This is a cd

Rena McGuire married Fred Road 31 Oct 1902 registered in Teller County, CO

Fred Roads married Mrs. Anna Brooks 22 Jan 1910 registered in Teller County, CO

Square W. Hilton married Mary VanOveren 18 Feb 1938 registered in Teller County, CO.

So, it looks like Rena McGuire first married Fred Roads, had a daughter Rena Roads, divorced before 1910 then married second Squire William Hilton.
