COBY -
common in
Israel, but only as a pet name for "ya'akov" (
JACOB)! not as a name on it's own. If this is where you got it, you can probably delete it.
SHAI :-) ,
YOCHANAN &
YUVAL -
are 3 common names in
Israel.
SHAI won't fit exactly into any catagory (either delete or put under Jewish). For the last two - why not "Biblical"?
YEHOCHANAN,
MATTITHYAHU -
a. Biblical
b. Historical
c. Jewish
d. all of the above.
