The Little Sisters of the Poor in Richmond are quite serious about their mission of caring for the elderly. Their selfless nature typically keeps them out of public view, but the recent canonization of their order’s founder, Jeanne Jugan, and their own 135th anniversary have them planning a rare celebration or two. They are returning to the Fan tomorrow, Jugan’s 217th birthday, for an open house at the Warsaw Condominiums, their home from 1877 to 1976. They will celebrate a Mass of Thanksgiving for the canonization of Jugan on Thursday at Cathedral of the Sacred Heart. They also will host a touring stage production about Jugan next month.
