You can add Keturah (keh-too-rah), Hagar's other name. :)What about the names in Hebrew? Sarah : sah-rah Sarai : sah-rie Avram / Avraham: ah-vrahm / ah-vrah-ham Yitzhak: yeetz-khak Ishmael: yee-shmah-elI like Sarah, Sarai is pretty too (and cute meaning "my princess"). Others are not really my thing.
"i" gives the idea of "mine". sara = princess, so Sarai = my princess. I don't know where "contentious" comes from. I have never heard of this meaning.
