In c. 1901 Irma Dugard was working for Corvus Lestrange. After the birth of his son, Corvus, the former sent the half-elf with his two children, the other being Leta Lestrange, to New York for them to be adopted by Mary Lou Barebone. Corvus was being targeted by Yusuf Kama, and he was sent away for his safety. Irma and the children posed as a grandmother with two grandchildren. They boarded a ship, where Irma met a woman travelling with her nephew. Presumably they became acquainted with each other, since the woman would call her by her given name. On the trip however, there was a commotion and Irma left her cabin to investigate it. Meanwhile frustrated with Corvus' constant screaming, Leta Lestrange exchanged her half-brother with another baby, the woman's nephew, who turned out to be Credence Barebone, saving the latter's life as the ship they were travelling on sunk during a storm. When Irma realised the ship was sinking, she went back to the cabin for the children, only to find Leta in the corridor with a baby, whom she presumed to be Corvus. She took the child from Leta and dragged her along as they left the ship. They escaped in lifeboats, but Irma never learn that Corvus died.
- Dugard is likely derived from the French "du garde" which translates to "of the guard".
