Fleur Weasley
Her history with Bill has been covered, but I will add that she worked for the Bank instead of the Ministry, and when she met the tall, red-haired man for a second time (the first being during the Tournament), she knew she must have him.
She stayed with the Bank, working her way up from her starting position, until she was forced to retreat into hiding with her husband. She did return to work following the war, but left just before her daughter was born.
