I have very old photos of what I think are a brother/sister: Hilda and Arthur Kunz from Milwaukee, WI. On back of photo is address: 2711 Grand Ave, Milwaukee. They may be related to the ZIEBELL family of Wisconsin as I found them with other very old photos of the Ziebell family. If you have any info on these two children please contact me. The photo must be late 1800s maybe 1900, hard to say. In very good condition.
