sister born in memphis tn 1-12-60 or 61 would love to find her

hello, my name is angie and i recently found out that i have a sister that was put up for adoption before i was born... my mother said her birthday was 1/12/61 she was born in memphis tn... my mother was placed in a home for unwed mothers at the time, i found this out from my aunt who doesnt remember very much because she was so young at the time.. i have another sister, she's two years younger than me and her name is julia, i also have a brother named kenneth he is 31 this year..... i would just love to meet my other sister because i feel like maybe i have been missing out on a best friend for almost 40 years now... if anyone out there knows anything or can help in any way please contact me...my mom did say that she named her katherine anne at birth but that could have been changed when she was adopted.....also my mothers name at that time was elizabeth anne smith ...she normally goes by anne if anyone can help please contact me ...thank you angie pounds
