Four of the grandchildren had yet to start their families, Ruth said, so the latter figure was likely to grow. And her parents would be delighted by that.
"Family is everything to them," she said.
Both her parents could perhaps count themselves lucky to have been born. Dorothy's father, Lance Corporal William McKee, served with the Anzacs at Gallipoli, and was one of just nine of his battalion who survived.
His "reward" was to be dispatched to the Somme, but he was one of the lucky ones who came home.
John's father Thomas added a year or two to his age so he could serve in World War I, then took a few years off so he could serve in World War II alongside his son, also Thomas, John's older brother, who was a member of the Long Range Desert Group in North Africa.
Both survived the war and returned to New Zealand.
Meanwhile John and Dorothy's 70th wedding anniversary was not all it would have been without the Covid-19 restrictions that had forced the Switzer Home to close its doors to visitors, but staff made sure that the occasion did not pass uncelebrated. And their family were very grateful for that.
"The care they are receiving is just fantastic," Ruth said. "The staff are wonderful to them, and we are very grateful for all that they do for them."
