Your grandmother’s family must have enjoyed good health and good fortune. Even today, getting 13 children to adulthood is an achievement, although they’re more likely to die in a teenage auto accident than from measles as a toddler.
I have ten children. Oldest is 27, youngest is 6.
They owned over a thousand acres which is a large farm in Florida. Of course the children grew up working very hard.
Mother was the youngest Daughter and had to see all her siblings and parents die. I still remember when Grandpa Mac died. Mother went into a closet and just cried and cried.
