The child was only in her mid-30s in 2008. How could her father possibly have had grandchildren through her at that time? And great-children when her daughter was not even 50 by now? Strains belief, unless she and her children started having babies at like, age 14. The  daughter was only born in 1972 or 1973, making her 36 or 35 when she met her father and had these "grandchildren." That's OK, if the kids were infants. But those infants were certainly not old enough to have children of their own by 2017 (the "great-grandchildren"). Why would anyone be overjoyed by children having children?
