And paper trail records which show a woman having her last child well into her late 40s or 50s, which are often covering up for an illegitimate grandchild.

I have mentioned this before, according to numerous trees, my grandmother's brother who was born in 1874  has a daughter born in 1500. Not only that, all that person's decedents have been added as well.

I have also found one of my ancestors giving birth in Essex in the late 1700s,  then nipping across the Pond and giving birth to another child six months later in America. They must have had supersonic ships in those days.

I was once told by an American,  when I queried some incorrect information on their tree, as long as the name was correct it didn't matter about the dates.

Yes, that was not unknown.
My mother was 41 when I was born in 1937, my older sister when mum was 38.
No other children ,mum and dad married late due to his ill health and inability to work .
They finally married in 1933, after almost 15 years courtship.
