Clarissa Jane Clair

I am looking for information on Clarissa Jane Clair.She was married to Dennis Charles Mills.I have a birth date for Clarissa of April 9, 1859 and a death date of June 15, 1930.I do not know if these dates are correct.The two children they had that I know of is-
1. Minnie Mae Mills(Grounds)
2. Florence Mills(Pratt)
Both of the daughters died in Michigan.
Minnie was born in Cordell Kansas in 1880.Any help would be great.Thank you.
