Geoffrey Swan

Geoffrey Swan is the husband of Helen Swan. He is the father of Charlie Swan and the grandfather of Bella Swan. He became the grandfather-in-law of Edward Cullen after his marriage to Bella, and the great-grandfather of Renesmee Cullen. He has had no role in the series.

It is mentioned in The Twilight Saga: The Official Illustrated Guide that he and Helen assumed they could not have children, so Charlie was an unexpected, but very welcome, suprise.
