What are the sources of birth and death dates?
Taking these sources into account, the correct date for death is November 4, 1485:

Well that certainly changes tree dating!
One more reference, easier on modern eyes.
Have to look at husband and daughter dates now.

This also helps. Adding missing daughter.
The testator married Margaret Tendring, the daughter of William Tendring (d.1500) of Stoke by Nayland, Suffolk, and Thomasine Sidney (d. 4 October 1485). See ‘Genealogy Report’, supra, p. 21.
Margaret Tendring was the sister of Dorothy Tendring, who married firstly Francis Southwell (d.1512) of Norfolk, Auditor of the Exchequer, son of Richard Southwell by his first wife, Amy Wichingham. See the will of Sir Robert Southwell (c.1506 – 26 October 1559), TNA PROB 11/43/577, and Gunn, Steven, Henry VII’s New Men and the Making of Tudor England, (Oxford: Oxford University Press, 2016), p. xx at:

Dorothy Tendring married secondly Sir(?) John Peryent (died c.1552), second son of Thomas Peryent, esquire, and Mary Brockett of Wheathampstead, Hertfordshire.
See the pedigree of Perient of Digswell in Metcalfe, Walter C., The Visitations of Hertfordshire (London: Harleian Society, 1886), Vol. XXII, pp. 156-7 at:

SUMMARY: The document below is the Prerogative Court of Canterbury copy of the will, dated 25 November 1555 [sic] and proved 10 April 1557, of Robert Forster (c.1482- 1545), esquire, of Little Birch, Essex, whose grandson, William Forster, was related by marriage to the family which owned the Blackfriars gatehouse purchased in 1613 by William Shakespeare of Stratford upon Avon.
I’m uncertain of the origins of Robert Foster of Birch in Essex, Esq. so left it off. He married Margaret Forster
Slightly different death date here:
She was one of the daughters of William Sidney d1453 of Kingsham and Penshurst, 2nd husband of Tomasine d1498 heiress daughter of John Barrington of Rayleigh by Isabel Tattam / Totton (+++Thomasine had m1 William Lunsford m3 John Hopton.
Sorry, there is a typo in my first post. The correct date is October 4, 1485: "Tomasina obiit iiii die mensis Octob."
https://books.google.nl/books?id=B5QdAQAAMAAJ&hl=nl&pg=PA40...
Here is another death date: "On 20 October according to the inscription on her brass at Yoxford"
https://books.google.nl/books?id=Y0hkh_WD01oC&lpg=PP1&hl=nl...
Also in this book there is a lot of information about Thomasina's mother, her spouses and offspring.
About Thomasina's husband:
William Tendering, esquire, of Harkstead and Holbrook, died in 1499
Unfortunately there is no image of the brass plate with the inscription here:
https://www.flickr.com/photos/52219527@N00/14248734873/
I'm afraid the brass plate is currently lost. Now we only have descriptions and images of this copper plate in various books.
In this image I see "Tomasina obiit iiii die mensis Octob."
https://books.google.ru/books?id=FJVZAAAAYAAJ&pg=PR16#v=onepage...
I think that "January 16" as the date of death on Flickr is a confusion with the date of death of her mother Thomasina Barrington: "She died 16th January, 13 Hen. VII. 1498."

I have attached the Sydney arms to the media for Thomasina Sydney, please take this profile photo.

Could you also update the profile of Thomasina's husband, William Tendring?
William Tendering, esquire, of Harkstead and Holbrook, died in 1499
It is doubtful if he was a member of parliament and was born in Stoke by Nayland, Suffolk.
At least there is no information on this here:

https://books.google.ru/books?id=FJVZAAAAYAAJ&pg=PR18#v=onepage...
I have attached the Tendering arms, please take this profile photo for William Tendering.

Done.
Can you look at the Tendring parent dates? They’ve gone a little crazy.
History of Parliament online doesn’t have him yet. So far this is what I got:
In 1499 a William Tendring left the profits of a tenement called Lucas (Lukes) to the priest for the time being to do service in the church of Our Lady in Little Birch for 21 years, especially in remembrance of the souls of William and his family. --- The undertenancy of little Birch Hall was held in 1276 from the Gernons by a Robert Verley and from 1325 or earlier by the Tendring family. William Tendring (1435-90) of Little Birch was MP Maldon, Essex 1478. [VCH would seem to imply he was father of this William, died abt 1500, who was father of Dorothy.]

This explains how Little Birch Manor came to the Forster family.
I think it was William the father who was the MP, and William d 1499 was father of Dorothy Tendring later Southwell.
