I've got no clue where in TN, maybe Memphis. Her dad's a racist, blind drunk and her mother is the most fantastic woman I've ever met. The two of them are divorced and have been for quite some time. Her mom lives in Reno, NV and her dad still lives in TN. I'm not sure where since his new wife made them move when a black man was seen walking in the neighborhood. I'm not sure if my dad talks like Marshall's mom, I haven't gotten that far in HIMYM. It isn't very obvious, if that's what you're asking. He spent nearly his entire adult life in the Army traveling and has probably lost his accent. He makes fun of my mother for her southern accent all the time.
