Robert Robinson was born in
Swaffham in Norfolk, on 27 September 1735, to Michael Robinson, a customs officer, and Mary Wilkin, who had married by license at
Lakenheath, Suffolk, 28 March 1723. His father died when he was aged five, but his maternal grandfather, Robert Wilkin, a wealthy gentleman of
Mildenhall, who had never reconciled himself to his daughter's lowly marriage, disinherited his grandson (leaving an inheritance of only ten shillings and sixpence). Robinson's uncle, a farmer, had sponsored Robinson's attendance at a school at
Scarning, near
Dereham, Norfolk, under Rev. Joseph Brett. This is summarised by
Alexander Gordon, who wrote, "The preaching of Whitefield drew him to the
Calvinistic Methodists; he dates his dedication to a religious life from 24 May 1752, his complete conversion from 10 Dec[ember] 1755." Hence, he was drawn initially to
Evangelical Methodism on hearing the
Calvinist George Whitefield; as late as 1758 he was spending some months at a
Calvinistic Methodist Chapel in
Mildenhall. He was then invited to assist William Cudworth at the Calvinistic Methodist Norwich Tabernacle, but after a matter of weeks seceded to form a new
Congregational Chapel in St Paul's parish, Norwich. In January 1759, he moved again, to Stone-Yard Baptist Chapel, Cambridge (St Andrew's Street Baptist Church). Early on, and throughout his life, Robinson pursued a detailed study of the Scriptures and early Christian authors, which soon convinced him of the inefficacy of
infant baptism, compared with the baptism of believing adults. This caused him some difficulty after he settled in Cambridge, with his large family of unbaptized children (see following). ==Ministry and later life==
