Trey MacDougal is the first husband of Charlotte York. They married but later got divorced due to the influence of his mother and personal difficulties.
Trey MacDougal is an attractive WASP, a charming gentleman with a pedigree as fine as Charlotte's. Trey is a cardiologist. He is noted to be an ideal catch even by her extremely picky standards. She marries him, but at one point makes out with the desirable gardener. Trey is upset and finds himself attempting to work on his tennis serve to distract himself. She then suggests separation. Charlotte later divorces Trey.
His family heritage is from Scottish and they are even richer than the Yorks. The undisputed head of the family is Trey's mother Bunny, who rules with an iron fist in a velvet glove. Bunny smothers Trey's manhood. He seems quite content to remain for life her tenderly beloved boy, she even used to sit by his bath and personally nurse him when sick.
