Melissa,
Here is what I found for you:
(marriages vol. 3, p. 88)
Willmett E. Thwing (father Rufus Thwing, mother Edna Sawyer) married to Clara J. Scovell (or Scovill, hard to read), parents John A. T. Scovell and Mary Oleson
Willmett E. Thwing, residence Lewiston, Columbia Co., Wis.
birthplace: Buffalo, Marquette Co., Wis.
birthplace of wife: Spring Valley, Fillmore Co., Minn.
place of marriage: Town of Beaver, Clark Co., Wis.
person performing marriage: T. M. Darton
witnesses: Florence E. Darton and Emerett Barker
date: mar. 22, 1885

If I get back to the courthouse soon I'll try to look up for any children from this marriage. Today I was just looking up deaths and marriages though. Hope this helps.
