Correlation of birth dates

[Jeuel]

I have a grandfather, father, uncle, brother, nephew and son (all male relationships) who were all born on a 15th. 

My other son and I have a birthday on 21st.

I did read somewhere that its statistically likely that mothers and daughters would share the same day of the month when they gave birth, something to do with menstrual cycles, but can't remember where.

However if you look at the overall picture of your ancestry you'll probably see a wider range.  I have family members born throughout the year on various days.  There is a tendency for a lot of people in my family on my mother's side to die in August, which I find a bit of a puzzle, since deaths are more common in the winter months.  But I don't think you can draw any conclusions, its just a coincidence.

There used to be clusters of births in September nine months after Christmas.
