taf, joe, vance: Thank you so much for all great info...What a great help. As you have snippets of time, maybe you could enlighten me on a few other points I've been struggling with.
*A deliberate forgery in the FitzRandolph pedigree was mentioned. Which part(s)? Is the Mary/Roger Bigod generation probably sound but not proved?
JOHN, UNPROVEN
*About the probably-correct-but-unproven, more recent generation which led to removal of this line from latest edition of The Magna Carta Sureties: Is this generation 10-11...a John is the father of Christopher FitzRandolph who m. Joan Langton -- John who was presumed to be a younger son of Sir John FitzRandolph and Joan Conyers of Spennithorne? Was this John identified through Magna Carta Sureties reference, "...the FitzRandolph pedigree in the British Museum starts with this John..."? See generation #11, here:

Is it likely that this is the same John (living in Nottinghamshire or Derbyshire in the time of Cuthbert Langton?) cited as enfeoffed by Cuthbert Langton? See c), here (Thoroton's Nottinghamshire, p. 296):
https://www.google.co.uk/books/edition/History_of_Nottinghamshire/xD4uAAAAMAAJ?q=%22cuthbert+langton%22&gbpv=1#f=false
What is the evidence that this John likely died around 1517 (have seen this reference in several places)? A will/probate documents...any tracing of what happened to lands he might have had, connecting him to son Christopher?
CHRISTOPHER "PARSON" FITZRANDOLPH'S WILL
*Separately, has the John FitzRandolph mentioned in the 1516 will of Christopher "parson" (parson believed to be another son of Sir John and Joan Conyers) ever been researched/identified/parentage been hypothesized? This John was under 21 when the will was made, and when his care was given over by the parson to an Antony Burgh. The will reads, "...and I bequeth to John Fitzrandolf x kye and a bull, plate and oyer goodys as moch as commes to xxti marc. Item I will that Antony Burgh be keper of the sayde John and his goodes to the tyme he come to xxjti yere of his age and gif to hyme mete, drynke and cloth, with somme lernyng, thenne the sayde Antony Burgh to delyver to the said John Fitzrandolf x kye and a bull, plate and other goodes to the valour of xxti marke, and if deth come to the said John or he come to the said age thenne the goodes to be geven to the kirke aforesaid or as they thynke best for the welth of my saule. Item I bequeth to Antony Burgh all my ferme of Langton Hall."
Could mention of a Burgh in the Kirkby parson's will -- perhaps related to the John Burgh of East Hawkswell, married to Margaret/Margery FitzRandall, presumed sister of the parson/daughter of John FitzRandolph and Joan Conyers -- be another indication of tie between the Spennithorne and Nottinghamshire FitzRandolphs? See History of Richmondshire, p. 327, here:

Do names of witnesses to Christopher "parson's" will give useful clues to anything? "...Item I bequeth to Thomas Wyngke one gowne cloth. Item I bequeth to Sir William Betson one gowne cloth. Item I will that Antony Burgh and Christofer Fitzrandolf be myne executours, they to dispose the residue of my goodes as thay thynk best for the heile of my saule. Thies being witnes, Sir Thomas Wynke, Sir William Beitson, Roberte Edwarde, Hewe Voluntyne, William Worth, and other moo.
Would it be possible or useful to research where Christopher "parson" was educated for the clergy? Do records of that kind even exist? Would they possibly mention his parentage? For example, see FamilySearch.org, Clergy of Church of England, "University Graduates" section, here (though our parson of course lived before creation of Church of England):
https://www.familysearch.org/en/wiki/Clergy_of_Church_of_England_(in_England)
CHRISTOPHER WHO M. JOAN LANGTON
*Even if the generations 10-11 connection can't be proved, does the preponderance of evidence around Christopher (d. 1570) point to the Spennithorne FitzRandolphs as his ancestral family?
*If Christopher's father John wasn't a younger son of John FitzRandolph and Joan Conyers, could he have been the son of a brother of Sir John FitzRandolph? How much is known about the male siblings of the Lords of Spennithorne and their descendants?
*Are Christopher's probate records published (1570 letters of administration granted to wife Joan and son Thomas?) I've seen references to these letters, etc., but wonder if they've been published or translated in full.
FITZRANDOLPHS, STRELLEYS, DARCYS, LANGTONS
Is it correct that the FitzRandolphs, Strelleys, Darcys, and Langtons were interconnected BEFORE Christopher "parson" was presented to the Kirkby-in-Ashfield parish through Sir John Conyers's advowson around 1490? If so, are these interconnections, and the advowson, solid evidence that Spennithorne and Nottinghamshire FitzRandolphs were closely related?
SIR BRIAN?
Who is Sir Brian FitzRandolph, who is named in at least one or two sources as the father of Elizabeth FitzRandolph, daughter of Sir Ralph FitzRandolph and Elizabeth (Scrope?), and who married Sir Nicolas Strelley of Linby, Nottinghamshire? (Strelley who is named in some Christopher "parson"-related documents). See Nottinghamshire History, end of paragraph #2, here:
http://www.nottshistory.org.uk/books/bonser1948/sutton19.htm
Also, see Thoroton's Nottinghamshire, Vol. II, p. 281, e), here:
https://books.google.co.uk/books?id=xD4uAAAAMAAJ&pg=PA296&lpg=PA296&dq=%22cuthbert+langton%22&source=bl&ots=qckAdD-UIh&sig=E4s4FGjV2S0oo_IdWkvTmbsGASs&hl=en&ei=5PVfTNWYONCT4gbMtLXSBw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CCYQ6AEwAw=onepage&q=langton&f=false#v=onepage&q=Fitz%20Randolph&f=false
These references contradict others to Elizabeth having married Sir Nicolas Strelley of Linby; see "Visitations of the North," p. 24, here:

DERBYSHIRE FITZRANDOLPHS -- WAY BACK
*Is there evidence that the Spennithorne-then-Kirkby-and-Sutton FitzRandolphs were related to the FitzRandolph family apparently established since 12th or 13th century in Derbyshire...that there was a far-distant common ancestor? Or is it possible that Christopher (d. 1570) didn't come from Spennithorne line at all, but from this old Derbyshire line? If this surname was rare in medieval and early modern England (as noted by Anthony R. Wagner, NEHGR, Vol. 99, p. 336), is it likely that these families were connected, even if distantly? See nottshistory link above, latter half of paragraph two, which reads:
"...In Rentals and Surveys A.D. 1295 in the P.R.O. appears the name of Walter Fitzrandolph when he paid a Fine of 3/2 for lands held of the king at Sutton-in-Ashfield and of his son Henry, who paid 5/-. The history of this branch is for many years obscure and it quietly lived its life at Sutton, and it is not again prominent till 1489, when in the Torre MSS. appears the name of Christopher Fitzrandolph as Rector of Kirkby when he died, and Thoroton in his account of Linby mentions Sir Brian Fitzrandolph whose daughter Elizabeth married Sir Nicholas Strelley, c. 1540, but died without issue."
My apologies that this is so long (and for many likely typos, etc.)! Is there any way to keep such details brief?
