Sorry to pick up this thread so late but my father, who passed away nearly 10 years ago, talked about being in a children's home also. What caught my eye in this thread is the location you talk about, Prospect and North. For some reason I thought my dad was in a home in Wauwatosa but he also mentioned walking through a field near his school, Maryland Ave. which is/was the school on Maryland just north of North Avenue. He said a lady often stood in the field waiting for him and said she was his mother. He knew his mother as did we after she got her life together but between 1930 when he was about 12 until 1940 when he shows up in the census with our now family name, (his birth name was Rowell), he is missing from the census. He definitely isn't with his mother. In 1940 he is living with another family as a boarder but I think was also friends with the family.
