Major Rathbone's accomodation in Hannover

[L Verge]

I remember not too long ago being chastised by a member of the Surratt Society for referring to Rathbone's position in the American Consulate in Germany. I was told that Henry never held such a post - period. However, this article and others that I have read since then certainly keep reiterating the fact that he was on diplomatic service in Germany. I'm so confused!
