I'm from the line of Anton John Hemmer and Katharine Mertzwiler. They were from the Belleville , Il. area. They were my great-grandparents. From all I've been able to find it looks like all of the Hemmer family came from Alsace-Lorraine. Even Katharine Mertzwiler's father ( Anton born 10/25/1841 )was born in Alsace.
