female born 7/83 in Washington DC ISO BMom

Hello. My name is Lisa and I was born (supposedly) 7/28/1983 at Bethesda Naval Hospital and was adopted through Catholic Charities in MD. I am searching for my birth mother and brother. All I know is that my BM was in the Army and I have an older brother and a younger half sister. My birth mother and father got divorced after I was adopted. Any further information is helpful. Thank you!
