The Munleys "closer to Detroit" are none other than my father, brother, and mother! I suppose I could certainly help you there.
They come from the Bay City group you wrote of by way of my father. So, my maiden name is Munley.
I see you are a Munley too. Do you belong in the Bay City group or are you from another branch of Munleys?
Some of those you listed already are definitely relatives. Perhaps we can pool our knowledge and help one another build our trees.
