Saw your query and noticed you are researching Aude. There was an Aude family that lived in Winfield. My ancestors moved from Leadville to the mining town of Winfield which is up Clear Creek Canyon. Not far from Leadville. There are two Aude children buried in the cemetery up there. Fredrick who died in 1885 and Georgina Katharina who died in 1887. I might have a little more info if you think they are related to you.
