I live in Memphis and I attend Our Lady of Sorrows. There is a Catholic church in Millington (St. William), but I’ve never been there. The main street in Millington is Hwy 51 and Our Lady of Sorrows is just south (approx 10 miles) of Millington on Hwy 51. We don’t have any Latin Masses. I’ve attended this church my whole life, so I guess I’m partial. I think it’s a beautiful church, but it’s not grand or fancy - we’re in sort of a poor part of town now. I grew up there, but moved away and I don’t like my neighborhood parish. I feel like our preist sticks to the rules more than some others. I suggest maybe you church shop a little and find the one you like the best. OLS is the closest outside of Millington, but if you’re willing to drive a while, there are plenty of others. Hope this is helpful.
