Hello Rosie, My name is Janis Peacock. I found your inquiry in the Genealogy Forum regarding Madeline Beecher Peacock.
I wonder if what I have on her will help you, it may or may not.Depending on what you need.
My interest in Madeline appeared when I found the name WM Peacock who I think was her husband and I have the names of some children they had.I was curious to find out how this Peacock family is or is not related to ours.We both lived in Iowa only we on the east end of Iowa with one exception, and they lived on the west end.
Donald Peacock was of interest to me as I did some research for the family of his wife and they are both buried in Cedar Rapids, IowaAnd Ralph was married to Ethel and she lived in Cedar Rapids as a widow but they are both buried in Des Moines Iowa. Within a year after Ethel passed away her daughter Suzanne passed away April 27, 2007.
If there is anything I might help with please write to me at my E-Address JanP424@yahoo.com
