Possibly quitting its use is just a sign of changing fashion - as with, say, Gertrude and Ethel in recent times - or it may be that if 'Jaket' was a badge of allegiance in the first place then the circumstances that prompted this had changed before the use of name lapsed.
It's hard to see what families might have been signalling to each other with 'Jaket' on its own, so that if there ever was such a motive then perhaps the names of siblings could provide a clue. Jacquetta of Luxemburg was probably forgotten by most before the late 16th century, though this doesn't necessarily mean that her given name would also fall way into oblivion. But in Tudor England we might expect that any kind of subversiveness or contrariness in loyalties would be hinted at only in extremely subtle ways.
My gut feeling is that only the first naming was reflecting national political associations, that of Jaket de St.Leger. After that it was just local family and social factors. A step-son used the name for a daughter, who gave the name to a daughter, and then it appears again in that woman's granddaughter.
Two other children of the step-son also used the name for their daughters. Jaket de St.Leger's first husband's nephew used it for a daughter (and her grandson had a daughter and granddaughter with the name), while her brother had a grandson who used it, bringing the total to nine with clear genealogical connections. Then there is Jaquet Marwood, who has no immediate familial link, but she named a son Seintleger Chapman so there seems to have been a social tie of some sort.
There is another mini-cluster of three (at least) that have a more tenuous connection - descended from the first cousin of Jaket de St. Leger's second husband, but that seems more likely just coincidence.
Robert, the illegitimate son of John Arundell of Trerise, used the name for a daughter and his mother's identity has not come down to us, so there could have been either a genealogical or social connection (the Arundells interact frequently with at least two of the families using the name - alternatively, the Arundell instance may be unrelated: the Arundells had a vassal family with Jaket as surname, and it could be that John's mistress was one of them, but this can't account for Jaket de St.Leger and her resulting cluster).
And now that I look at it again, I don't think these families quit using the name when I thought - the last ones I have in the cluster are all three
children or siblings of a 1620 visitation pedigree provider, so the 'disappearance' is more likely an artifact of the availability (or lack thereof) of genealogical details on those families, coupled with me not having done a thorough survey. Along these lines, I just checked the Devon Lay Subsidy, 1543: a Jacot' Conybeare and a Jaket Sowdon. No known connection to the 'cluster'. Also I find a mini-cluster associated with the Rolle family with no known connection. It is looking like this was used more broadly than my initial survey would indicate.
And while we are talking about odd Devon names, there is also Zenobia, which seems to have been a local fad, as I am finding a dozen or so unconnected examples in Devon and Cornwall 1620 visitations.
