Tamar (תָּמָר) comes from the Hebrew word for "date palm" — the tall, slender, fruit-bearing tree that has been central to Middle Eastern agriculture and poetry for millennia. Three biblical women bear the name, including Tamar, daughter-in-law of Judah, ancestor of David.
Tamar is among the most popular girl names in Israel today. It is rising in Western records, sitting in the U.S. top 800 and climbing. The Georgian Queen Tamar (1184-1213) is also a famous bearer.
Tamar reduces to six — the number of fruitfulness.
