William Cornwall

William Cornwall (1786–1860) was an Irish Methodist.

Cornwall was introduced to Methodism by Gideon Ouseley and became a minister in 1814. He was noted as an excellent scholar in Irish.

In 1819 he was visited by a Connemara woman who explained that Ouseley had not reached as far west as her home but that if he or Cornwall should do so a warm welcome would be assured. Despite this, the Connemara mission never thrived.

He was stationed at various places around County Galway such as Lawrencetown and Tuam. He retired in 1849 and settled in Galway the following year. He died in 1860, survived by his wife, Anna Maria, who died in 1910, aged 89. Both of them were buried in the Methodist plot at the back of the chapel in Victoria Place, Galway.
