Dear Newsgroup ~
Reviewing secondary sources, it appears that there were at least three John de Gatesden's.
The first was Sir John de Gatesden (died 1262), who married Hawise de Courtenay (died 1269), widow of John de Neville. He left a daughter and heiress, Margaret (or Margery) de Gatesden, minor in 1269, wife of John de Camoys, Knt., of Flockthorpe (in Hardingham), Norfolk, and William Paynel, Knt., Lord Paynel.
The second was John de Gatesden (died 1258), who is called "the younger." He is identified by VCH Sussex as being the son of the first John de Gatesden (died 1262). I believe they were closely related but they were not father and son (as will be seen below). The younger John left a widow, Margery (living 1259), and a daughter Margaret, born about 1246 (aged 13 in 1259). John de Gatesden the younger at his death held the manors of Trotton and Didling, Sussex, and Gaddesden and Stanbridge (in Leighton Buzzard), Bedfordshire.
VCH Sussex 4 (1953): 32-39 (sub Trotton) states that Margaret daughter of John de Gatesden the younger is the one who married John de Camoys. But this is an error. I say that because Margaret daughter of John the younger was born about 1246, whereas Margaret (wife of John de Camoys) the known daughter of Sir John de Gatesden (died 1262) was still a minor in 1270.
Elswehere Cussans, History of Hertfordshire, Dacorum Hundred, pg.120 states that Margaret daughter of John de Gatesden the younger married another John de Gatesden (died 1290). This could be correct. Whatever the case, it appears it was this third John de Gatesden who died in 1290, who left a daughter, Joan (born about 1267, aged 23 in 1290), wife of Richard le Chamberlain. I assume he is the John de Gatesden who gave a quittance to the manor of Lathbury, Buckinghamshire sometime before 1282, which property Joan Chamberlain later claimed as her right in 1316.
That John (died 1262) and John (died 1258) were closely related is indicated by the fact that the manors of Trotton and Didling, Sussex went to Margaret, daughter of John (died 1262), who married John de Camoys, whereas the manors of Gaddesden and Stanbridge (in Leighton Buzzard), Bedfordshire descended to the Chamberlain family. Lathbury, Buckinghamshire was also claimed by the Chamberlain family.
Besides the difference in ages between the two Margaret de Gatesdens, I find that there are two lawsuits which involve Margaret de Gatesden, wife of John de Camoys, with the other heirs of her mother, Hawise de Courtenay.
1. In 1274 Walter de la Hyde and Joan his wife sued John de Camoys and Margaret his wife in the Court of Common Pleas regarding the manor of Norton [Fitzwarren], Somerset, excepting one virgate of land, etc..
Note: Joan de Neville, wife of Walter de la Hyde, named above was the daughter of Hawise de Courtenay by her 1st husband, John de Neville.
2. In 1280 Peter de Montfort and Maud his wife and her half-sister, Hawise le Veel, sued John de Camoys and Margaret his wife regarding the manor of Norton [Fitzwarren], Somerset, which John and Margaret they said had no entry except by John de Gatesden (father of Margaret) who unjustly disseised Joan de la Mare, mother of the said Maud and Hawise.
Note: Maud and Hawise were daughters of Joan de Neville, wife of Henry de la Mare and Walter de la Hyde.
Procs. Somerset Arch. & Natural Hist. Society 28 (1882): 197–200 includes a discussion of the manor of Bradford-on-Tone, Somerset, which proves that John de Gatesden [the husband of Hawise de Courtenay] who held the manor of Bradford, Somerset, is the father of Margaret de Gatesden, wife of John de Camoys. This John de Gatesden also held moieties of the manors of Norton and Heckford, Somerset, which explains the two lawsuits above. Regardless, the Somerset proceedings account confuses Margaret, wife of John de Camoys, who was a minor in 1270, with the other Margaret de Gatesden, daughter of John the younger, who was born about 1246. Conversely, Carthew, Hundred of Launditch & Deanery of Brisley 1 (1877): 238–241 correctly identifies that Margaret de Gatesden, wife of John de Camoys, is the daughter of John de Gatesden who married Hawise de Courtenay.

So far, I haven't seen any evidence which confirms Cussans' claim that Margaret, daughter of John de Gatesden the younger, married another John de Gatesden. If the couple were near related, such a marriage would typically be banned by church laws concerning consanguinity. However, it would explain how this John de Gatesden's daughter, Joan Chamberlain, would be heir to the Gatesden family manors of Gaddesden, Lathbury, and Stanbridge. However, I have another possible theory which should be explored. It appears that John de Gatesden the younger (died 1258) had a full brother named Richard de Gatesden. If Margaret daughter of John de Gatesden the younger died without issue, her inheritance would fall to her nearest heir of the full blood, namely her uncle Richard de Gatesden. If Richard de Gatesden had a son and heir, John de Gatesden, he could be the one who was the father of Joan de Gatesden, wife of Richard le Chamberlain. As far as I can tell from Honors and Knights' Fees, Joan Chamberlain's father, John de Gatesden, first surfaces in 1282. As such, there is plenty of time for the Gatesden properties to go from Margaret daughter of John de Gatesden the younger to her uncle. Richard de Gatesden, and thence onto Richard's son, John de Gatesden. I like this theory as it explains how the Gatesden properties at Gaddesden, Lathbury, and Stanbridge remained in the Gatesden family, although supposedly there was a female heiress in the chain of descent.
That Margaret, daughter of Sir John de Gatesden (died 1262) was still a minor in 1270 is proven by a record of that date found in the Court of the King's Bench. In Easter term 1270, Richard, chaplain of Bradford, Somerset, was summoned to answer the king that the king permit him to present a suitable person to the church of Bradford, which was vacant and in the king's gift by reason of the custody of Margaret, daughter and heir of John de Gatesden, being then in the king's hands. Richard further said that whereas the church was vacant and was moved by an action in the King's court regarding the advowson of the said church between Thomas de Audham and Isabel his wife and Hawise, widow of John de Gatesden, who held the manor of Bradford in dower, and that during the contention between them, he worked from the time of the voidance of the same [which] the Bishop conferred on him the said church.
The above record is abstracted in Notes & Queries for Somerset & Dorset 14 (1915): 254–257. The original can be found at the following weblink:

The fact that Margaret daughter of Sir John de Gatesden (died 1262) is styled his "daughter and heir" in 1270, it is clear that she was his only surviving heir in 1270 and that the other Margaret (born c.1246) can not have been his grand-daughter as has been frequently alleged in print.
So how was Sir John de Gatesden (died 1262) related to John de Gatesden the younger (diedc 1258)? Below is a record which may explain their relationship.
In 1236 John de Gatesden made the fine of 25 marks that the king grant to him the custody of the land and heirs of John de Gatesden, his nephew. Reference: Henry III Fine Rolls Project, E 371/4, 21 HENRY III , 21/8 (available at
https://finerollshenry3.org.uk/content/calendar/roll_004E.html#it008_010).
I believe that the adult John de Gatesden named here in 1236 is Sir John de Gatesden (died 1262). The unnamed heir of John de Gatesden the nephew named here would be John de Gatesden the younger (died 1258). If so, this arrangement would make SIr John de Gatesden (died 1262) the great-uncle of John de Gatesden the younger (died 1258) and his brother, Richard de Gatesden (living 1259).
