@Bekki:My mother (Mrs. Watson) was one of the houseparents in Senior Girls during the 1960's & 1970's.She had also been a houseparent in Toddlers for some years before.I remember clearly my foster sister calling ACCH the "chillie coop" and your cats Love and Peace and the Senior Girls cottage.(In fact, I remember a lot of things about the place as I pretty much grew up there!)Mom is still living, 87 years old...but doesn't always remember things as well as some of us these days.You girls were a VERY big part of her life!
Also: the address is 11805 Lima Road, Fort Wayne IN 46818.I'm not sure there is any archival information available there, but it's worth a try. It is now Youth Services Center, with a completely different structure than ACCH. You might also try the township trustee's office in Fort Wayne.The Allen Co. Public Library has a couple pictures of the old bldgs. on their website, too.
