Ian, do you really mean Herefordshire rather than Hertfordshire, or is that just a typo. Brian's link says Chiswell Green, Hertfordshire.

The earliest reference to cricket in Hertfordshire is from 1732, but it wasn't ever really well established there (even now its only a minor county). Before the 1830s cricket was really only popular south of the Thames.

Some variant of rounders is probably more likely.
