Margaret Carrico married to Henry T Bradley is the sister of my 3rd great grandfather James Carrico. I came across your post and tried to help in your research. What might help you is I looked at the most possible year Nannie Colloher would be in and 1880 I searched Kentucky records. Although I could not Find Nannie, I did see that that Calloher is also Spelled Calaher, Kalaher. This may help. I found a John Calaher born in 1821 in Ireland and is in a Hospital in 1880 in Louisville Kentucky. My Carrico line has various Spellings, Even my 2nd great grandmother real name was Julie Dora Carrico, But married as Dora Carrico to London Bartley. Again I hope this helps and I will keep this surname in mind. Anything I come Across I will send to you.
