My mother's sister gave birth to a set of twins (a boy and a girl), then the girl twin gave birth to a set of identical twin girls. My other mother's sister was pregnant with twins but one didn't grow so it didn't make it. My mother had her children but no sign of twins. But, to our amazement, my mother's 3 grandchildren also gave birth to a set of twins each. Only one set of identical twins were boys. The other 2 sets are boy/girl.

I have heard there are more. When we tell the doctors they tell us this is not hereditary. We say what a load of rubbish. How can one family have so many twins and it not be hereditary?

Our eldest twins are 49 years old and the youngest are 2 years old.

Is there any one else with this many twins?
