I find it interesting that you have the Walsh surname and also the Dunn surname. My grandfather was Victor Joseph Walsh born in Westfield, Wisconsin-Marquette.Co.I inherited alot of old photos after my grandmother died and among them was one of a Myrtle C. Dunn,high school photo dated June 7,1909,studio in Princeton,Wisconsin. I have no idea who she is.If you would like to see the photos here is the link
