I'd say that during the 1880s Susy and her family changed over, broadly speaking, from Susie to Susy. The latest I find her signing herself "Susie" is in 1882. Her father continues to write "Susie" throughout that decade, and later. There may be more specific information that I don't know about. In any case, the MT Project's "A Family Sketch" anthology follows the spelling of the source documents without alteration.
