The eldest of his 3 sons, Douglas James, heir presumptive emigrated to Italy in 2012.
Second son, David Angus, is shown as single.
Third son, Robert (Bob) Cameron, married with 2 daus. Cannot locate births in GRO. Is it possible that he is no longer married to Natalie HEAP as in Debrett's online?

There is a clear indication on Sandra KIRKWOOD (widow of David) of a granddau, Abigail Florence K. born 2018, but I cannot work out which of the children she is the dau of.
