Saw you are interested in RODY from Balduinstein to US/Canada. I too have a BUECHER & a EGENOLF emigrating from there, to southern Indiana, US, in 1864. I just found a website that links to the local records office--in case you are still looking:

"Balduinstein Lahn Homepage von Manfred und Angelika Richter"
Maybe this will be useful to you.
