 The Burdets founded Loseby parish church and gave its advowson to the Order of St Lazarus based at Burton Lazars which they supported for many generations until relations soured in about 1290 when the Order started to appropriate part of the parish's tithes.Riots broke out over the ensuing years, Loseby's vicar was excommunicated and William Burdet's actions "polluted" the churchyard by bloodshed in 1297.Gradually calm was restored to the parish and in 1298 Sir William Burdet agreed to pay for the reconsecration of the church and reconfirmed his family's grants to the Order but relations were never the same again.
