John Davenport (1597-1670) was born in Coventry. He attended Merton College and Magdalen Colleges in Oxford, but never received a degree. He ws ordained and became a curate in London and then the vicar of St Stephen's, Coleman Street. Initially Davenport conformed to liturgical practices but as anti-Calvinism and ceremonialism spread in the Established church he became a non-Conformist. In 1626 he helped to organise the Feoffees for Impropriations - the buying of church livings so that could be given to those with puritan leanings.
He eventually left England for the Netherlands in 1633. In 1637 he left for the New World. He was invited to the Westminster Assembly in 1642; other New Englanders that were invited included John Cotton and Thomas Hooker. He was unable to attend as he was the only minister of New Haven.
