I just read this one from the Library, Texas Angel, by Judith Pella. It was a wonderful story. If you've heard/read the Love Comes Softly Series. This is kind of like that story.

Description:

A devastating revelation about her past deems Angela Hearne a slave and sends her away to Texas. There she meets evangelist Benjamin Sinclair, who's aiming to teach lawless pioneers a thing or two about retribution. But he's the one who learns a valuable lesson in winning souls to Christ . . . and opening his heart to love. 320 pages, softcover from Bethany.
