Hi Alan,
Yes this is the same Henry Lembcke, my great grandfather. I have a photo of his 3 sisters who stayed in Germany. I'm now trying to make a connection to their descendents so that perhaps I might identify which sister is which knowing that Maria König is a daughter of one of them. I may be able to learn more on another trip back to Salt Lake as I have identified the parish for Barnkrug since I posted this email nearly 5 years ago.
