Lorraine Heath (like this not that)

I love love the Lorraine Heath books {Parting Gifts} and {Always to Remember}. Both stand alone HR westerns. However I read several books from some of her Regency and Victorian series and wasn't getting the same vibes at all.

Can any fans of these books point the way to other similar books? Doesn't have to be another western necessarily, more like similar MMCs or plot style.
