A notice placed in Tuesday’s The Daily Telegraph by the Brooksbank family read: “Brooksbank, George. Died on 18th November.
“Loved all the good things in life but especially his wife, friends, boys, daughters-in-law and grandchildren.
“Private family cremation, memorial details to be announced.”
The poignant reference to his grandchildren comes after he was able to meet baby August, who was born in February.
But the family suffered heartbreak when Mr Brooksbank died in the run-up to the family gathering on Sunday.
He had been ill for some time and is said to have never fully recovered after catching coronavirus last year.
August was baptised in a rare double royal christening in Windsor with his second cousin, Lucas, the son of Mike and Zara Tindall, in the presence of the Queen, who has been under doctors’ order to rest for more than a month.
In June last year, Eugenie thanked NHS staff for saving Mr Brooksbank’s life after he fell ill with Covid-19.
At the time, Eugenie, her husband, mother-in-law Nicola and brother-in-law Tom were warned to prepare for the worst when Mr Brooksbank was put on a ventilator for five weeks.
