I believe the last name of Nancy who married Henry is Rose. I am descended from his brother Peter Ryan (b. 1821) who married Sarah Rose (b.1829) 1844 in Rhea, TN.(not proven same two)
I found on the internet death records from TN. showing Nancy's death in 1915.
Grandma Sarah died in 1917...

I believe these two are sisters who married brothers.

I have a copy of Grandma Sarah's death certificate which states father as Joel Rose, this is a brick wall. Many have tried to connect Grandma with a Joel and cannot find. I myself am still looking.

Good Luck!!
