Their daughter Martha is widowed and living with her parents.
In 1880 Nancy is living with her daughter Sarah Kendrick in Robertson, TX (Sarah A married Richard H Kendrick in Robertson , Tx on 29 Dec 1875.) Duncan has passed away and it looks like he died in Robertson, TX.

I beleive that I have found some of William's, Martha's, James' and Sarah's children.(although another researcher believes the James I have found is the son of a David McPhail. This needs further researched.)
