Mystery Monday - Help Us Find Our Siblings

Today I am going to do something a little different. As a follow up to my previous posts Surname Saturday - Huffman and Thankful Thursday - Meeting My Biological Family, my new found biological family has made it clear that they want to find our other siblings who were adopted into other families. By my biological family, I mean all of them, not just my brother and sister. This is an open letter to our missing siblings. If you were adopted, please read on. If you know someone who was adopted, please share this with them. If you are a member of the genealogy community, please, please share this post and help us to get the word out in the hopes that it will help us find our missing family members.
We are looking for children born sometime between July, 1955 through early 1963. One of our missing siblings was born in Chicago probably at Cook County Hospital. I was left at the Chicago Foundling Home, however, my brother or sister could have been left at a different orphanage. The other sibling(s) would have been born in Louisville, Kentucky, and may have been adopted into a family in either Kentucky or Southern Indiana. If the children have obtained a copy of their non-identifying information that they are entitled to by law, their mother's age would match a birth date of 9 November 1935, she was a waitress and listed her ethnicity as German and Irish and German and Dutch (although that is not entirely accurate so your information may be different but should contain German) on my paperwork.
Please help us by sharing this post. Below is our open letter to our missing siblings.

Dearest brother and/or sister,

Our family is incomplete without you and we want to find you so very much, but, due to privacy laws we cannot. Because of this, you have to find us. We will try our best to help you find us. Please know, we love you and all we want is the chance to know you. There is a hole in our hearts and souls that only you can fill. We have missed so many years already, so please hurry because we miss you in our lives. Help us make our family circle complete. You may be wondering how to do this now so we will tell you. Illinois opened up adoption records to adoptees in November, 2011. That is how our sister found us. To our sibling born in Chicago, you can obtain a copy of your original birth certificate that will have the name of your biological mother on it. If her name was Shirley Huffman, born in Rossville, Illinois, the you will know you are our sibling. Go to this website, download the PDF form linked at the bottom of the page, complete the form and mail it along with a check to the address on the website. To our siblings in Kentucky, you will not have the option to do this, however, our sister Cathy's adoption was not sealed by our mother, so maybe your records were not sealed either. Kentucky law and your options to find us can be located here. You have an option to obtain your original adoption records so all you have to do is write them. Another option to find us is a DNA test. Our sister Cathy has her DNA on 23and Me or Family Tree DNA but you can have your DNA tested anywhere and upload your raw data to Gedmatch free. If you are our sibling you will show up as a family match with our sister Cathy and will be able to contact her at any of the 3 sites. We are doing all we can to find you. The rest is up to you. Here is a picture from our joyful reunion with our sister. Do not be afraid because there is nothing to fear - the entire family wants to welcome you with open arms. Please find us!

Love, Your brother Barry and sisters Cathy and Michele
