I am helping a friend try and find some family. She has a 1/2 sister by her father prob born around 1960 or 1961. Her father was about 28 in 1964 - born in Iowa in 1936.. He had been in the army. He was in building construction. He was in the process of a divorce in 1964.
Her birthmother was 18 in 1964. She was born in Texas around 1946. Her dad was an attorney. She was living with birthfather at time of birth. Birthmom had been married before.
Grandparents on both sides were alive in 1964. Roach or Roche dad born around 1911, and mom around 1913.
