Hi,

Here is a quote from the Family History of Craufurdland:

15.John Craufurd of Craufurdland married twice in his lifetime, first to Helen Chalmers of Gadgirth, by whom he had a son, John, his heir, and three daughters: Janet;Agnes and Helen. Secondly, he married Christian Wallace of Auchans, and widow of Mr James Ross of Whiteriggs and thereafter Lady Dreghorn. Together they had a son Robert, and a daughter Catherine.Robert got from his father the lands of Monkland, but his son, John, died without issue shortly after his father, and the lands returned to the family of Craufurdland. He died in 1612 aged 42.

Can anyone explain to me how the 'and the lands returned to the family of Craufurdland' works? Does that mean that the title wouldn't go to one of John's brothers? If not, how far back do I need to go?

Any help appreciated!

Janet
