The first name Jamy is ♀ female and ♂ male.
Jamy is a unisex short form of James, a variant of Jacob (originally Ya’aqov / יַעֲקֹב).
Jamy means “may God protect” and “holder of the heel” (from Hebrew “‘akév/עָקֵב” = heel) or “supplanter” (from Hebrew “‘akáv/עָקַב” = to follow/to supplant), because he was born grasping the heel of his first born twin brother Esau and he bought his birthright to supplant him.
