I'M A MESSIANIC JEWESS, all my sibling's, bar our older sister from our Dad's first marriage have very CURLY hair.  Our younger sister had a rag mop from a baby.  SHE was nothing but curls,while my brother and I had Aryan traits as children. All of us are blue eyed. Our older sister may have curly hair.  Anyway, it's a moniker of our ancestral ties to Egypt and how YAHUSHUA HA'MOSHIACH ELOHIYM lead us to the land of milk and honey.
