My parents told me they gave me the only name they agreed on at the time: Abby.
Not Abigail, just Abby, because Dad thought Abigail sounded prissy and he did not want a prissy daughter. It did not really help, but he did try and I was eventually nurtured out of the prissiness.
I get amused when people occasionally call me Abigail. It does not bother me – I view it as a nickname. If they ask, though, I smile and tell them I’m Abby, not Abigail, but they can call me either one.
Abby comes from Abigail which means “my father is joy” or “my father’s joy,” depending on how you translate the original Hebrew.
