Lucien Jean-­Baptiste (Péan) Svendsen - Evidence of Lucien's father?

Greetings,

I work for Geni and we've been contacted by a relative of Johan Severin Svendsen suggesting that Johan was not Lucien's father, but rather it was a man named Charles Christian Svendsen. This person provided some evidence for that claim. Can anyone find and upload evidence that Johan was, in fact, Lucien's father? I hate to start picking at users' individual trees but since these people were born more than 150 years ago, they are in the range of what Geni considers the public sphere where it becomes increasingly important that we rely on genealogically-sound evidence for everyone's benefit. I appreciate any information you can provide to support the information here.

Kind regards,

Mike at Geni
