Augustus Henry Aldborough Henniker (1837-1906) - the surname Stratford was added sometime later - married Lillias Grant Holroyd (nee Cambpell) in Pictou on 23 August 1859 (the marriage was recorded later on 24 April 1860, Prince Edward Island).
Lillias Grant was 18 years older than Augustus Henry and a widower when they married. He was the son of Sir Augustus Brydges Henniker and Elizabeth Henniker-Major, of Thorham Magna, Suffolk. He was the only one amongst 9 siblings to marry abroad.
Lillias Grant Campbell was born in Morvern, Scotland, in 1819, the daughter of John Campbell (Royal Navy lieutenant, known as 'captain John Cambpell) and Catherine McLean (daughter of the 5th Laird of Drimnin, Allan McLean). The family emigrated to Canada around 1833-34. Capt. John Campbell died 11 May 1834, and Catherine on 2 December 1861.
Lillias had been previously married to the Hon. Joseph Holroyd, of Wither or Wyther Grange, Wyther Hall, Leeds, Yorkshire, who died on 4 March 1854, P.E.I. They had at least 3 children, Hannah Sarah, Lillias Louisa, and Arthur Warburton.
The second marriage didn't last long. Augustus Henry Aldborough Henniker left Lillias Grant and apparently had 'gone off with her daughter' in June 1861, according to a private diary published in 1964.

"Henniker has run away from his wife, Holroyd, and gone off with her daughter"
https://islandnewspapers.ca/islandora/object/guardian%3A19640831After he left Canada in 1861, he went to New Zealand as Henry Aldborough Stratford, mentioned on 15 Nov 1862 in the Otago Daily Times, issue 283, page 6.
He married Annie Penrhyn Thomas in 1867 at Cromwell, NZ and they had a son Augustus Brydges Henniker Stratford, born in 1885 at Wellington. Annie died in 1901. Augustus Brydges died in 1918, wounded in action at the Somme.
In 1901 Henry Aldborough Stratford 'officially' changed his name to August Henry Aldborough Stratford-Henniker (Page 2 Advertisements Column 3 West Coast Times, Issue 12022, 23 September 1901, Page 2)
Augustus Henry married again in 1902 to Margareta Eliza ('Daisy') Wickes.
He died in France (Mentone) on 27 August 1906.
Lillias Grant was known and buried as Lillias Grant Henniker, widow (1900, P.E.I). I couldn't find any record of a divorce, which makes me think that Augustus Henry was a bigamist when he married Annie Penrhyn Thomas.
The 1881 Canada Census lists Elizabeth Holroyd (21, born in Ontario) in the household of Lillias G. Holroyd (60, born Scotland), along with Hannah S. (34, born P.E.I.), Lillias L. (32, born P.E.I.) , Arthur (30, born P.E.I.), and Alexander McLeod (26, born P.E.I), at Lot 33, Queens, Prince Edward Island.
I haven't been able to find anything else about Elizabeth Holroyd.
What happened to Elizabeth Holroyd? Was she Augustus Henry's daughter? Did he take her to England or New Zealand? Any help finding her is appreciated, thanks.
