Importance of the Wargrave Church

From the text:

Day, the author of Sandford and Merton, lived and—more credit to the place still—was killed at Wargrave. In the church is a memorial to Mrs. Sarah Hill, who bequeathed 1 pound annually, to be divided at Easter, between two boys and two girls who “have never been undutiful to their parents; who have never been known to swear or to tell untruths, to steal, or to break windows.”
