Lost and Found and Lost again...

well to start I was adopted by my fathers parents...I had a sister who passed away 5 days after her 18th birthday, we had the same mother and father and both of us our grandparents adopted, I had only my birth father through prison bars...and mention my birth mother only a few times with no major information. Well when I was 16 she (birth mother)contacted me and my sister with a phone call asked if it was ok for her to send us a picture of her and some things we said yes, and later when my sister was killed in a car accident I seen the car to have closer and found numerous return to sender Easter, Christmas and letters address unknown that my sister had sent to our birth mother....I was born April 27th 1978...my sister was born Dec 5th 1979, I believe my birth mothers name is Kathy Hamilton or close relation to that and she has a sister named Ann or Anna.... :hippie: I hope some one has advice or hope of getting in contact with her again to let her know my sister is gone and where she was buried.
