Please forgive my long delay in responding. After the 2 March 1840 death of Hannah (Abercrombie) Nash; John Nesbitt Nash maried Mary Bolt on 7 July 1840. John & 2nd wife Mary (Bolt) Nash had a son, James Nesbitt Nash, b. 16 July 1841 and died 1865.That is all I know of him.
If you still are interested in names of all the children of Colvill & Mary (Lindley) Abercrombie, I will be happy to give the names and dates.
