Since it was stipulated by Don Rosa that her father was a Coot and her mother was a Gadwall, it's not clear if Ludwig Von Drake is related to Elvira Coot through her father or her mother.
Deoarece a fost prevăzut de către Don Rosa că tatăl său a fost un "Coot" iar mama o "Gadwall", încă nu este clar dacă Ludwig are legături cu Elvira prin mama sa sau prin tatăl său.
