Sir William Parker

The father of Sir William Parker is unknown, as is his birthplace. His mother was named "Agnes" [from her MI plaque], but her dates and maiden name are also unknown.

Sir William Parker has an MI at St Giles, but it was placed there by his son Henry Parker as an elderly man & he appears to have confused his father's year of death [known to be 1504 from other sources].

William Parker was knighted by Richard, Duke of Gloucester during the 1482 war with
Scotland. When Edward IV died, William was part of his funeral procession. A month later he is
present at the coronation of Richard III. Richard III makes him one of his privy councilors and he is
one of Richard III’s banner bearers at Bosworth

The year 1491 marks the beginning of open favor of the Parkers by Margaret Beaufort. Sir
William’s son Henry is taken into her household. This action places the future Lord Morley into
the heart of the Early Tudor court in the entourage of the king’s mother, a woman whose political
influence was eclipsed only by that of the king himself.
Sir William fell subject to a bout of insanity in 1493, the precise nature of which is unknown.
It appears he had recovered by 1496 when he was one of twenty-five knights who served at the feast that Margaret Beaufort gave for the Bishop of Lincoln in honor of his elevation, a dinner attended by Lord Hastings and Cecily Plantagenet, sister to the queen. This is the dinner that Henry Parker described so vividly in his Account of the Miracles of the Blessed Sacrament mentioned earlier.
The last mentions of Sir William note that he again fell subject to insanity in 1502. The king
“noted courses to be taken for the discharge” of Sir William’s debts in 1503. Sir William died soon
after, within the year. His memorial inscription is clear that he died by some violent act whose nature is not recorded.

Most modern scholars who study Lord Morley agree: the dates on the memorial plaques are off .
For example, the 1528 death date for Alice Lovell can’t be correct since her will was proved in 1518.
The 1520 death date for Sir William Parker can’t be right since his widow Alice was remarried by
1505. The death date of 1480 for Elizabeth de la Pole is nine years before we find her in the hearing in 1489 to settle her jointure.
If Sir William Parker was really 56 when he died around 1504, then he was born sometime
around 1448. His approximate birth date presents a problem for his mother Agnes since her death
date on her memorial plaque is 1440, eight years before she gave birth to Sir William.
Since I have found no contradictory information so far for Alice St. John, I will assume that her
age and death date are correct, especially since they appear reasonable. As already mentioned, the 1476 birth date for Henry Parker, Lord Morley based on his memorial plaque may be five years too early.  The alternative 1481 birth date is good only if: 1) the dinner described in the Account of the Miracles of the Sacrament was really the celebration feast for the new Bishop of Lincoln, and 2) Henry Parker really was 15 years old at the time. What isn’t discussed by the present-day scholars is the reliability of Henry Parker as a source. When Henry Parker wrote the Account of the Miracles of the Sacrament, he was an old man two years from death. It was his last work. Given his age, a fading memory can not be discounted.
Starkey made a point that Henry would not have said he was fifteen if he had really been twenty
at the Bishop of Lincoln’s feast. But what if Henry exaggerated his age downwards? After all, leading
twenty-five knights to serve a feast sounds a lot more impressive if he said he was fifteen rather than twenty. Alternatively, what if he mixed up memories of two different feasts? He was Margaret Beaufort’s sewar and cup bearer for almost two decades and he probably saw a lot of formal celebratory feasts. It wouldn’t be at all surprising if he mixed up details when he was writing as an old man remembering events more than 50 years in the past. The point I would like to make here is that we need to add a third assumption if we are to believe the 1481 birth date: that Henry Parker remembered and related the event correctly, which is not a given for an elderly man.
It’s obvious that Henry Parker had to be a source of some or most of the information used on
the memorial plaques. The potential problem of an old man’s memory has to be considered when
looking at the errors in the dates. But even if Henry Parker’s memory was still sharp in the last few
years of his life, he himself may have believed his information was correct even if it wasn’t. The parish register system didn’t exist before the last decade of Henry VIII’s reign so unless a date was written down somewhere, Henry Parker’s own memory of ages and death dates may have been flawed.
