Looking for half siblings

I am looking for an individual who posted on this site about 7 years ago. I just found the posting today. I have once again decided to start my search for my half siblings. There was an individual who posted on here that her biological mother was Diana Rose Rains whose DOB was 5/7/52. She stated that she had three half siblings who were named at birth: Carrie Marie Cruz (7/24/80), Angelina Marie Sanantonio (7/8/76) and Lester Nordgren (11/3/74). She believed that two were born in Los Angeles County and one in Orange County possibly. She was also given the birth name of Angelina and her DOB is 6/24/79. I believe I am the Carrie that she is looking for and would like to get in contact with her to exchange more details. I am now married, so my last name is Garner and I am currently living in Korea where my husband is stationed in the military. I would love to know my half siblings as I have a son who would like to meet new family members and I was raised as an only child so having siblings would be exciting for me. If anyone can help me out, I would appreciate it. It's easier to reach me by email at cgarner423@gmail.com. Appreciate all the help
