Which branch are you researching?

My Gentner family came to the US from Germany and settled in the Springville, NY area. Some of them later moved to Michigan, but I am mainly interested in the Springville branch. There is also another group of Gentners in West Valley, NY, that I haven't been able to connect yet. Oddly, my mother (whose maiden name is Gentner) grew up with a best friend who was also a Gentner, but we have yet to determine if and how they are related!
