- 1902 - 
Archibald Hume Campbell, born July 1902, was the grandson of Robert Hume Campbell and Mary O’Connell, a New Zealander, who married in 1869.
Robert and Mary had five daughters, and when Robert died on the 27th January 1921 he was succeeded by the eldest, Madeleine Elizabeth Hume Campbell. As Glendaruel had been sold by this date, the title “of Glendaruel” was in name only. Her sister, Lilias Marianne Campbell, married Yorkshireman Charles Henry Horsfall in July 1901, and he took the additional name Campbell.
LIlias and Charles’ son, Archibald Hume Campbell, was the correspondent in the Campbell of Glendaruel papers, 1979-80.
