I was helping Jacqueline out by looking up some references for her. I am a volunteer at WMU Regional History Library and try to watch the local Kalamzoo County postings for items that I may be able be of help for out of towners.
I suggest to repost your message to Jacqueline's original message as I bet she would be very interested.
Your message will also be of interest to my wife who does have history to the Minar family of Doster, MI. I will show this to her when she returns.
