Per Debrett's 2008, he and his wife are childless.
His older brothers have children but there are no males. The heir,
Hon Richard Oliver and his wife have 3 daughters but their only son,
b. 1986, died in 1989. The second son, Hon Charles Ernest and his
wife also have 3 daughters.
Next in line would be their uncle, the current Lord's brother and his
family.
Good news on this front. The brother, Hon. Richard Morgan, b. 1931
has 2 sons. The elder son has 2 sons, b. 1984 and 1992. The younger
son has a son, b. 2000. There is no danger of this barony becoming
extinct anytime soon.
