Looking for Bmothe and 1/2 sister

Hi My name is Kim, I live near Boston Mass. My birthdate is September 23, 1968 and adopted February 12, 1969. . The name on my birth certificate is ___ Cayton; but in the adoption file they refer to me as babygirl or Janice Cayton. My bmom's name was Virginia Close Cayton from Cambridge, her birthdate is 5/19/46. I was told she has a twin sister Irene Close Kelly. According to the Adoption file she had a daugher named Deborah born on 11/2/63. Also, there might be a younger sister named Kim but I cannot confirm that. If any of this rings a bell, please feel free to email me at kimc456@verizon.net. I don't want to intrude on your lives, I would just like some information we don't even have to meet if you don't wish to, but I would love to if you are willing. Thanks Best regards, Kim
