The KY death index for 1911-2000 is now online at
http://userdb.rootsweb.com/ky/death/search.cgi and lists 1753 Ballards.
Ancestry.com has put online a "Gene Pool Index" at
http://ancestry.com/search/rectype/inddbs/4725.htm, with free access until
11 July. "The Gene Pool was created while gathering genealogical data for
use in the study of human genetics and disease" and it contains 20 million
names. Having used it for a day I would guess that it is drawn almost
entirely from the LDS Ancestral Files and should be used with all the
caution appropriate for that source. It can be searched in ways which are
much more flexible than those allowed on the LDS website. You can search
for any combination of surname(s), given name(s) and location(s), which
means that you can enter together the surnames of a husband and wife and a
county name and/or state abbreviation.
