No one has mentioned Barbara's parent's role in this. From the version I know best (Johnny Moynihan when he was with De Dannaan):

Get up, get up, her father said
Get up and go and see him
O father dear do ye not mind the time
You told me how to shun him?

Get up, get up, her mother said
Get up and go and see him
O mother dear do ye not mind the time
You told me how to slight him?
