I need suggestions on how to find a family. Census won't work because all family members were not born until 1963. the family lived in the Buffalo NY area in 1970.

Mother born in 1923, Father born in 1919, male child born 1947, female child born 1947, m child born 1950, f child born 1953, m child born 1960, and f child born 1963.The families last name was Becker. The father was an engineer, mother was housewife, oldest son was in construction, oldest daughter was secretary. Oldest daughter had a male child born 1/28/70 birth name was Brian Patrick Becker. He was placed for adoption through Our Lady of Victory.

Any ideas?
