I don't have any information, but since you have your birth name, you could have your sister try to obtain your hospital birth records, per the instructions here:
http://www.plumsite.com/shea/name.html you could also use one of the public record sites to try to locate your mother...although you may have to pay...I checked the Indiana marriage records and couldn't find them...And there are probably court records somewhere, especially if you were taken away
this is a possibility from whitepages:
