My mother Suzanne- nee: Lacaillade ( fluency in French is excellent) say it means "keeper of the quails". My mother has an interesting family story related to the name lacaillade passed down in family history.
Great time 2 or 3 grandfather changed his name from Godard to lacaillade after leaving France with his wife.- she was of higher station than he and was the quail keeper on her father's estate.- ran away to Canada to NB than to Quebec.
