Did Stephen Miss Speak in Acts

Ok anyone have a good explanation for this question ,Acts 7:1-4 1 And the high priest said, "Are these things so?" 2 And Stephen said: "Brothers and fathers, hear me. The God of glory appeared to our father Abraham when he was in Mesopotamia, before he lived in Haran, 3 and said to him, 'Go out from your land and from your kindred and go into the land that I will show you.' 4 Then he went out from the land of the Chaldeans and lived in Haran. And after his father died, God removed him from there into this land in which you are now living.
This scripture states Abraham's father died be fore he left Haran, BUT Gen 11:26 says Terah was 70when Abram or later Abraham was born,Gen 11:32 say's Terah lived to 205 years of age,Gen 12:4 Abram was 75 when he left Haran so if Terah lived to 205 then he was 145 when Abram left Haran and that Terah lived another 60 after Abrams departure. one other thing if Terah had died then would the term your fathers house be used wasn't it his house supposing Abrams the oldest. So did Stephen miss speak or was he possibly quoting from a Targum or some other type of paraphrase.
