The BBC news website has a story saying that the remains believed to be
of King Alfred are to be examined.

In particular, it says "Ms Burns said DNA testing [...] could be an
option but finding a descendant of Alfred would be trickier as he died
almost 600 years earlier." Am I right in thinking this is basically
nonsense?
Mitochondrial DNA testing isn't possible as Alfred was no-one's mother,
his only known sister, �thelswith, is believed to have died childless,
and not enough is know about the family of Alfred's mother, Osburh, to
know of any more distant matrilineal relatives.
Y-chromosome testing doesn't immediately seem a whole lot more
plausible. All the published genealogies I've seen show the House of
Cerdic dying out with Edgar the �theling, some time in the early 12th
century.
However, I've seen some speculative genealogies that make the extinction
of the male line move recent. For example, A. Anscombe's 1913 paper,
"Pedigree of Earl Godwin", makes Harold II a descendant of �thelred I
through �thelweard 'the Historian'. If Anscombe's theory is correct,
and if �thelweard's descent from �thelred is patrilineal as is often
suggested, that extends the House of Cerdic at least to Guttorm
Ingesson, son of Inge II of Norway, who died in the early 13th century.
Are there any other plausible hypotheses that extend the patrilineal
descent more recently, or even to the present day? If there happen to
be such speculative descents, it seems to me that there might still be
value in Y-DNA testing of them against the supposed bones of Alfred. A
negative result wouldn't convey much information. (Are the bones not
Alfred's? Is the hypothetical descent incorrect? Did some other
"non-paternity event" occur?) But a positive result would be fairly
persuasive evidence both that the bones are Alfred's and that the
speculative descent is correct.
