Abandoned baby searching

My name is Stacey and I am an adoptee looking for my biological family.  After a lifetime of searching and the recent miracle of DNA testing, I am now, finally, VERY close to finding my birth mother/father.  Here's my story:

I was abandoned as a newborn, in a car in a mall parking lot in OK City on June 8, 1971.  My umbilical cord was tied with a string, and I was wrapped in a blanket and left in the front seat.  When found, I was determined to be approx 8 hours old.  I was soon placed with 2 wonderful families, (1 foster and 1 adoptive), who have loved me and made me into the woman I am today.  I have no regrets and wouldn't change a thing about my life.  I am loved and healthy and now have a family of my own.  

The reason for my plea here is because I am closer to finding my bio parents than ever before.  Through the help of DNA and countless individuals that have graciously given their time to help guide me, we have been able to narrow it down to a little over a dozen candidates.  If these individuals are willing to test, I will need to provide them with DNA kits to help me get closer to my goal.  It is very possible that my bio parents have already passed, and also very likely that my bio father doesn't even know I exist.  But by testing as many family members as I can, I will be able to narrow it down.  I am not sure how many DNA kits I will need in all, but they cost approx $99 each.

I have had so much support from family and friends through this process, that I am already truly blessed.  They have read my ups and downs on FB and kept me going and uplifted the entire way.  I can't thank everybody enough for their love and support.  I know that all of this is happening in God's perfect timing and that I will soon be able to put the last puzzle piece of my story in its place.

Thank you :)
