I agree the best places to look are the on-line indexes.
Jewishgen, Billiongraves, Findagrave, the few
Israeli locations that are online, Tel Aviv, Sgula, Haifa,
Hod Hasharon, Izkor (Min of Defense), there may
be more now.
The major problem I've found is miss-indexing or
missing entries on all of the above data bases.
Israeli listings will include the date of burial
and the *father*'s name. Israeli's, after about 1960 are recorded
at Bituach Leumi - *but* requires the Israeli ID number and is not
open to the public.
About mistakes of indexing, the PC only came out in the 1980s, and became
a tool in the 1990's. People recorded what they saw on the stones, but
some spelled the name >from the sound, so a vav-vav may have become
a bet. A David may have an extra yod, as Dav-i-d.
I have found (in 2014), for instance, approximately 30% of the Izkor
data base has some discrepancy with the stone, name, parent's
name, army/police rank and even location of the grave.
Tel Aviv, I searched for a grave, I had a name in English and date of
death. The index recorded the DOD, but the Dalet as a vav. So 34 was
listed as 36. I only found the problem when zooming in on the photo I
took, it was not apparent at the grave site.
A kibbutz. The graves are under trees and covered with leaves. I asked in
the office if they knew the site of a grave. They claimed the person was
not there, since only members are buried in their cemetery. The person
was the sister of a member and was buried at the site.
Jewishgen. The Netanya entries do/did not have the
Gush/area. But the data is very important as it gives
both the Hebrew and English names. I have used that
on almost every search.
