I have seen the herro family tree and corresponded with Mike Herro. This is the same Pohler family, and he got some of the information from me. He is related to the Hvall side of the family if I remember correctly (my paternal side). My grandfather was a Hvall and my grandmother a Pohler. I'll have Ancestry send you an invite to my Hvall-Garner tree. I've had my my local LDS library put microfilm of the Als Sonderberg area on permanent hold. It is just full of Poher and Kjer information. I'll get back to you with the microfilm numbers so you could get them sent to your local LDS library to research. Hard to believe there are no longer any Pohlers living there at the present time.
