As noted by tutuzdad, AnyWho is a service of AT&T, rather than Google.
As for information on the person's age, AnyWho states:
"Please do not contact AnyWho concerning listings or personal
information from paid search sites (which can be accessed from some of
the AnyWho result pages). These listings are not part of the AnyWho
database; please contact the paid search sites directly if you have

"IF YOU ARE SEEING LISTINGS THAT CONTAIN AGE OR BIRTH DATE, PLEASE
NOTE THAT YOU ARE NO LONGER ON THE ANYWHO SITE. SEE PARAGRAPH ABOVE
FOR MORE INFORMATION."
"Help: Privacy Listing Process"
If you click on "More Info on --- ---. Free Preview!," you're taken to
a US Search page, which lists ages for some people. If you click on
"20-Year Personal History of --- ---," you're take to ZabaSearch,
which lists some birth dates. These appear to be affiliate
advertisements; the sites to which AnyWho links may pay AnyWho for
referrals that result in revenues for those sites.
AnyWho also states:
"The Service may provide, or third parties may provide, links to other
World Wide Web sites or resources. Because AT&T has no control over
such sites and resources, you acknowledge and agree that AT&T is not
responsible for the availability of such external sites or resources,
and does not endorse and is not responsible or liable for any Content,
advertising, products, or other materials on or available from such
sites or resources. ..."
"Terms and Conditions" [# 13]
The AnyWho pages I have cited include contact information concerning
terms and conditions and removals -- you might try writing to that
same address concerning your question. I don't see an obvious contact
address at AT&T for the issues you have raised; but you could try one
of those contact methods.
