I am working on your last posting and will email you privately with the stray thoughts and data I may have.
I have no reasonable doubt but that your husband is related to the Bavarian Uhlfelders. I have not found any others. There are Uhofelders in other lands but they all trace themselves to the Bavarian Uhlfelders.
You are a fortunate woman to have married such a wonderful person....I don't think you should tell him that becasue some of us get swelled heads.
