What does Dorothy tell Hester about the Furnivall sisters, Grace and Maude, and the foreign musician?

Dorothy tells Hester that she heard a story from neighbors that Grace and Maude had both fallen in love with a foreign musician their father had hired to play for them. The musician taught their father to play organ, and while the lord practiced, the musician would go to the woods with either sister. Ultimately he married Maude in secret and they had a child.
