searching for siblings removed from parents care in the early 70's

last name was Martin. Parents were married at the time of my siblings birth. I believe they were adopted in 72 or 73. they were adopted by seperate families. one was a boy the other a girl. the boy was around three, the girl around a year when adopted. I was adopted at birth in 1973. they were removed shortly befor my birth. please email me at bjbuddy4@hotmail.com
