Although Hank Pym is known for his high-profile relationship with fellow hero and Avenger Janet van Dyne AKA the Wasp, she wasn't actually the first woman he was married to. She was the daughter of the Hungarian geneticist and entomologist Janos Trovaya and a political prisoner in Hungary who managed to escape to the United States of America. Whilst there she met, dated and eventually married Hank Pym. On their honeymoon - which was spent back in her native Hungary - she was kidnapped and killed by communist agents, but "she" returned to Pym after that, only to be revealed to an agent of evil organisation A.I.M. There have been comments that she strongly resembles Janet van Dyne, so it's fairly clear that Pym has a type!
