biographical and/or anecdotal:
One hand has *Helena of humble birth and a barmaid in Bythnia. Perhaps this story originated when *Helena was forced to divorce *Constantius I at the orders of Diocletian so he could marry Theodora.
The other hand states that *Helena was princess of Britain. This story might have come into being since it didn't suit to have one's saints being barmaids.
In any event this story was popularized by Geoffrey of Monmouth.
