I am looking for my mom's 1/2 sister who was born and placed for adoption about 1937 in CA. She probably would not know she has a younger sister about 10 years younger than her. My mom's non identifying info from state of CA gives very little info on her 1/2 sister. Family was from MO. Family was Mostly Irish, short, blue eye, brown/light brown hair. My mom's birth mom was born about 1917. She had four sisters and one brother. My mom was born and placed for adoption northern CA area.
