I feel that I can safely say that any parent would experience an extreme amout of sadness upon the death of their child. For the rest of their lives, the memory of their child would stay with them....
The proper way would be to said 'are mom and dad'.
Their father, Milton Wright went from 1828-1917. Their mother, Susan Katherine Koerner, went from 1831-1889. They died around their son's glories.
She would be your great grandmother.
