This is absolutely fascinating that I stumbled upon this posting! I am the owner of the House in Waukesha on N. Charles St. that S. E. Gernon and his wife Agnes built and what I presume, raised their family in. I have been collecting little bits of information when I find them about the family and home - trying to create a great scrapbook of history on the property for myself and any future owners.
I would love to discuss the family with you and or exchange photos of the home with you as I am looking to see what this home might have looked like in 1907. I purchased it in 2007.
My wife an I are now the proud owners of this wonderful home and really enjoy putting together pieces of the past.
I was also amazed to see that another person actually found the local burrial sites of the entire family. That would be woth a visit, to once again add a few more pieces of the puzzle to the history of this home we live in.
I look forward to hearing from you in re: to anything you might know about the Gernon family.
