Popular 19th century American religious hymns?

For the past six months I have been amassing a collection of early to mid-19th century American hymnals to arrange hymns selected from them for performances at Civil War re-enactment church services by a small woodwind ensemble. As of today, I have arranged 63 hymns which are far more than the ensemble will need for any one church service. After our rehearsal the question was asked as to whether there were any popular hymns that I might have over looked from the period from 1830 to around 1865. So I turn to Yahoo Answers with the hope that there is an expert on hymnology who might offer titles of hymns that he or she knows were popular during that time frame.

I an NOT interested in the stories behind the hymns or in popular songs of the time period. I'm only seeking titles of popular American hymns found in early to mid-19th century hymnals that were sung by American congregations. Once I have a title, I usually can locate the music in the hymnals that I've collected or on-line. I await a response from a hymn expert. Thank you.
