The Andrew Marvell connection

Andrew Marvell is one of the two most famous sons of Hull (the other being William Wilberforce), known more now as a poet than as the MP for the city.  His statue stands near the grammar school which he attended.  But here we refer to him as Andrew Marvell junior, because his father was Master of the Charterhouse.
The Reverend Andrew Marvell was Rector of St German's in Winestead, a small village not far from Hull.  Winestead was the seat of the Hildyard family.  While they were living there, Marvell and his wife, Anne Pease, baptised 5 children; Anne (1615), Mary (1616), Elizabeth (1618), Andrew (1621) and John (1623).  The youngest died shortly after his first birthday, on 20 September 1624.  Ten days later Rev Marvell was appointed Master of the Charterhouse.  So the future poet and MP came to us when he was 3 years old.
A blue plaque on the Master's House tells the world that it was home to this famous Marvell.  But was it?  We know that the original hospital buildings stood until 1642, when they were demolished during the siege of Hull at the start of the Civil War.  It was, at least partially, rebuilt in 1649 and completed in 1673.  It is highly likely that The Master's House was part of that rebuilding.  Another, much-publicised, connection is with the mulberry tree in the garden, where the young Marvell is said to have sat.  The tree does seem old enough, but we have no actual evidence.
Marvell's connection with the Charterhouse was forgotten for a long time as a result of the failure of historians to do proper research.  A particular culprit was Augustine Birrell, a Liberal politician who turned to essay-writing and wrote a book about Marvell in 1905.  He described Marvell senior as Master of the Grammar School and made no mention of the Charterhouse, causing confusion which was still very much in evidence in 1921 when the city held celebrations for the 300th anniversary of the poet's birth.  Festivities centred on the school, and a commemorative book contained a long essay by Birrell repeating the error.  It wasn't until Pierre Legouis went back to the sources in the 1960s that the truth was told.  (The moral of this story - don't trust confident amateur historians.)
When he was only 13 young Andrew left for university in Cambridge.  His subsequent career has been extensively written about, and although he became MP for Hull in 1659 and remained in that post until his death in 1678, he spent little time here.
His mother died in 1638; his father remarried but died himself in 1641.
