The Lucinda I found as married in 1880 but without her husband on the form was married to Andrew J. Brown...he is the missing husband. His death year of 1896 was mentioned elsewhere in this thread and is attached to him every tree I viewed, but I don't know the source for that year.
I have Calvin's wife as Estella. I did find their 1900 record, and they were in Ashland, District 15, page 79, starting with line 60.
