Continuing the difficult birth theme, even today grateful parents sometimes name their newborn after the doctor / nurse / midwife.
Perhaps the first two words are intended to be a noun phrase, rather than two separate nouns. So it might mean "by healer Julianna". Any Latin experts around? If there was a Julianna or Julian who was in the medical profession in the area, that would fit (No idea how common doctors etc are at that time, so there might be one by coincidence. )
