Looking For Birthparents of Husband, born 11/5/1973

My husband has asked that i help him in his quest for information on his birth parents. My husband was born on November 5, 1973 in Bethesda, MD. Birth mother was 26, Catholic, with brown hair and brown eyes, and of Italian descent. Birth father was in his 30's, either separated or divorced (with three previous children), blond, blue-eyed, Catholic, and of Slavic descent. At this point, my husband just wants some information about where he came from. We are happily married with two children of our own, and truly want nothing more than to gather some missinf pieces. Thanks!
