After being separated from her family and moved frequently around the region, Nelly voices strong opinions. She is described by Rev. Francis Dzierozynski, S.J. as “an excellent cook and industrious servant and house keeper and sacristan…her only fault, is too long tongue; for the rest, the best servant.”
