I’ve been searching the terrific database of parish records for Cheshire and for each set of records that are uploaded, there are  notes from those doing the transcribing.

In the parish of Tilston St Mary, I came across this one:

Since I have been Rector of Tilston there have been
Burials 737
Christenings 829
Weddings 209
May 16th 1770
(Signed) James Richardson Rector
More Christenings than burials 107
Ten Christenings for nine burials
Five out of nine live to be merries [marrried?]
17 females born for 10 males
About one in forty die in a year.

James Richardson MA was rector of this parish from 1719-1773.

If you’v got ancestors from Cheshire, have a look at the Cheshire Parish Register Database. The user-interface is not gorgeous, but once you get there, click on Database on the left hand nav-bar and then you can search by event (Baptism, Marriage, Burial)
