Alvin J. Shartle (1867-1948)

I noticed you lacked biographical info on A. J. Shartle at http://www.hymnary.org/person/Shartle_AJ1. A fairly good biography can be found in the Historical and Biographical Annals of Berks County, Pennsylvania, by Morton Luther Montgomery (Berks County, Pennsylvania, J. H. Beers & Company, 1909).
