Spring was descended from a wealthy Lavenham clothier who owned property in 130 places and in 1523 bequeathed the considerable sum of £200 to complete the magnificent tower of his parish church, adorned with 32 shields carrying his recently acquired coat of arms.
In 1624 Spring was elected for Suffolk, becoming the first of his family to sit. He kept a copious and informative diary of the fourth Jacobean Parliament, covering the dates 19 Feb.-27 May 1624. The surviving manuscript is a fair copy evidently written up after rather than during debates. Unfortunately one chunk, covering the period 16 Apr.-22 May is now missing; Spring noted that ‘for what wants of the days past between the last and this following see part of it in a book of notes hastily taken in the House, and another part in another like it and so taken’, neither of which is extant.
Spring did not stand at the next two general elections. In 1628 he was ‘generally thought very wise, godly, and able for the place’ by the Suffolk electorate, but he deliberately absented himself from the county court, and his close friend Sir Nathaniel Barnardiston* was returned with Coke.
During the 1630s Spring founded two lectureships, but these were not welcomed by Harsnett’s successor, Bishop Matthew Wren. Writing to his close friend John Winthrop in New England in 1636 Spring declared that he dared not tell him ‘what I think and would you know’ about the state of affairs.
