This research is still ongoing, but I thought some of you might
be interested in a very basic outline of the descent of the family.
It has been extremely difficult to establish proof of descent from
father to son for long periods, and it is highly likely that on at
least two occasions the manor and lordship passed to a younger brother
or more distant member of the family. Established links are indicated
by a "|" sign between names.
The family of Rudston (of Hayton) almost certainly originated in Rudston,
East Yorkshire, and to have been connected with the household of de Gant,
whose family held an estate around Bridlington. Possibly the marriage in
1142/43 of Alice, sister of Gilbert de Gant, to Roger de Mowbray brought
a branch of the Rudstons to Hayton, where they later held an estate of
the Mowbray fee : the picture is uncertain, since Osbert the Sheriff/
William le Tourniant/Millicent the heiress & Herbert the Chamberlain/
Herbert de Moreville and Richard his son are all attested at Hayton before
any of the Rudstons. The 1185 "Inquest of the Templars" also reveals a
"Ricardus de Galhetoft", which may be for R. de Morville.
At any rate, the Rudstons are well documented in at Haydor, in Lincolnshire
(Trehoe Wapentake) from c.1160 to c.1225; holding, towards the end of that
period, of the fee of Creon. Around [1197x1201] Walter de Rudston gave land,
a mill and his capital messuage at Hayton to St. Peter's York (York Minster),
but until I can examine the Cartulary of Warter Priory at the Bodleian, or
Farrer's MS transcript of it, I lack the details of other transactions carried
out by Walter in Hayton in this period.
But to the pedigree, fwiw :-
1. Roger.       Attested [<1161] - 1180. Connected by marriage to the family 
                 of [de Bovington?] - "Rabot fratre suo", 1176
     |
2. Walter.      Attested 1199-1219. Obiit before 1225. 
                Connected by marriage to the family of de Hessle
                A brother, Stephen, attested [1174x1184]-1205.
     |
3. Roger.	Attested 1219-1252.
     |
4. Walter.	Attested 1252-1285.
5. John.	Attested 1293-c.[1318-1326]
     |
6. John.	Attested 1315/16-1349.
7. Walter.	Attested 1361-1391; 1396/7-1404.  
		Probable ties of marriage to the family of Ughtred.
8. Robert.	Attested 1392-1398; 1408-1446/7.
		Probable ties of marriage to the families of Salveyn & Palmes.
		Possible links by marriage to the family of Rocliffe.
[9. Walter. Only attested in 1444.]
10. Robert.	Attested 1472-1489.
      |
11. Walter.	Attested 1500-1509; obiit 1509/10.
		1 brother (John, later Lord Mayor of London), and 4 sisters : 
		but I have some residual doubt as to the relationship.
Beyond this point the pedigree gets much more elaborate, because better
documented. It must be stressed that the pedigrees of the family in all the
published works - including the Visitations - are completely fictional up
to and including the father of Walter[11], and many of them contain errors
down to the early 1600s.
If anyone would like to see it, I can also provide a fragment or two of a 
pedigree for the Rudstons of Rudston, although my aim there was to try and
establish how early the two branches of the family went their separate ways
(assuming they had a common origin). So far, I have not found a common
ancestor, and there remains a slight possibility that the place of origin of
the Rudstons of Hayton was Radston (Northants) and not Rudston (Yorks).

================================================
Trying to establish a coherent family tree for the Rudstons of Rudston
is even more difficult than for the Rudstons of Hayton. The problem here
is that the vill of Rudston comprised three manors, and the tenants of
each manor seem to have adopted the surname "de Rudston" at will during,
and in some cases after, their period of tenure. The situation is not
helped by the relative paucity of first names - William, John, and Malger
being favourites.
There is, however, a well-documented descent of one of the families,
thanks to a wrangle over the right to the advowson of Rudston church
which is found in the Eyre Rolls for 1218-1219 (Selden Society Vol. 56,
“Rolls of the Justices in Eyre for Yorkshire 1218-1219”; pp 102-105,
Case No. 246;  p148, Case No. 340 - “Pleas and Assizes at York 1218-1219”.
See also Case No. 1126.).
So a partial pedigree of the Rudstons of Rudston for the period c.1160-1230 :
[7]. Radulfus de Ruddesteyn	    fl. c. 1150?
    — Robert de Ruddesteyn (see 8)  “son of Ralph” – Coram Rege, 18 Henry II 
				     (1172). Holder of knight’s fee in 1166?  
    — A brother or sister	    “Stephen his nephew” (Brid. Cart. p.159
[8]. Robert de Ruddesteyn	    fl. c. 1160–1172.  see 1219 case
       — Malger de Ruddesteyn (see 9)
       — William de Rudston         Brother of Malger the knight (Brid. Cart.) 
					fl. c.[1155–?(1203)]
         — John de Rudston	    “clerk” – attested 1216 and 1219; rector 
				    of a moiety of the church of S. Ferriby

				     remarried John de Brigham, who died <1225 
           — Amicia/Avice/Hawisia, heiress : married Geoffrey de Tournay 
					     before 1227. Avice living 	
					     (widowed) 1254, 1268.
	   — Sir Richard de Tournay, kt.     held 8 carucates at Rudston of 
					     the Luttrell Fee (c. 1250)

		Attested [1170–1184] – 1208. Dead before 1219. 
         — Alan de Rudston     	“.. clearly not Malger’s heir and was
