Youngest great-great-great-grandmother

Of the many cases of great-great-great-grandparents reported, the youngest person to learn that their great-grandaughter had become a grandmother was Harriet Holmes (Canada) (b. 17 January 1899), who was aged 88 years 50 days when she became a great-great-great-grandmother to Brian Bursey on 8 March 1987. Ann V. Weirick (1888-1978) of Paxtonville, Pennsylvania, USA, received news of her great-great-great-grandson Matthew Stork (b. 9 Sept 1976) when aged 88. All six generations were living.
