I went to see what was on-line concerning the origen and ethnic connections of the name Ehn. It was the name of my great-grandmother, Catherine Christina Ehn, who came from Sweden with her husband, Charles Henry Walden, who had changed his name from Olafson. In the 1880's they settled in the town of Leroy, Michigan, where he became the town clerk,a grocery store owner, and the Lutheran pastor. There is hardly any information on-line about the name, so I thought I'd add a link to the search.
