Sorry I can't be of much help but I can tell you what I found out. First the offficial name was the Milwaukee Home for Dependent Childern. Seemed very difficult to locate even on Milwaukee County and WI.State Historical web sites if you do not the correct name. Milwaukee Co. Orphanges didn't turn anything up. You can locate a photo of the remaining build by doing a to Goggle Map seach. It will give you a great view of the remaining building. The site also says this "
Milwaukee County Home for Dependent Children--Administriation Building is a building located in Milwaukee County, in the city of Wauwatosa. This building was listed as a historic place according to the laws of the state of Wisconsin..." So at least you know it is still there. Another site: http://www.poorhousestory.com/WISC_PhotoScrapbook.htm
has an older photo and states the building have been torn down. I don't think that is correct since the Goggle map seach give you a great street view. I have some photos I got off another web site I will be glad to send them to you. Not sure I can do this using Ancestory, but we can work it out.
Anyway I did attempt to contact some of the Milwaukee Co folks in attempt to locate the records..but no luck. So you might want to contact the Milwaukee Co. Historical or Genealogical Societies and see if they can help.
I have to admit I lost interest as I was doing this for one of my relatives and they lost interest so I dropped the seach.
Just to share with you, my mother was in a Masonic Orphanage. I located the orphange in OR. The buildings were all there and in good shape. When I aked to see the records they said the records were in the attic and they wouldn't go up there as there were too many Bats.
Anyway good luck in your seach. If loacate the records let me know.
