Judy wrote to the Dyersville Historical Society asking for Henry's obit. It's short but gives a lot of info--altho it doesn't completely clear things up, since every generation seemed to have multiple variations on the name John Henry! (The photo might or might not be him, but the vintage seems possible)...
Judy writes: "My current theory is this: There is a B.H. Naber and Anna Marie Tegla Naber, presumably husband & wife buried at the cemetery at New Vienna according to Find a Grave. According to Find a Grave, J.H. is their son. There's a bit in the St Boniface Centennial Book of 1995 about John Herman (J.H.) that confirms his middle name and also that of his father: Bernard Herman Naber. I'm thinking I can also tie this information in to the B.H. Naber and 3 sons: Theodor, Henry (John H) & Gerhard (John G) that immigrated into New Orleans that you have previously found. According to a marriage record of the son Bernard D - he was actually a Bernard Theodur!!! The only thing I've had trouble resolving with that is Gerhard's age. There seems to be a discrepancy of birth year between what was on the ship manifest and what was on his tombstone".
See? It's complicated!
🌺THANKS, Judy 🌺
