She was the daughter of Patrick Garrity and Catherine Glinnan who came to the United States about 1847 where they joined other Irish Catholic families at Victory, Saratoga County, New York. Patrick soon established a grist mill at the base of the dam on the Fish River which flows between Schuylerville and Victory Mills. He operated the mill for many years.

Marcella Garrity married Henry Baker. Their daughter Josephine was born in 1877/78. She married Thomas Nacy, son of Thomas Nacy Sr. and Elizabeth Moran (Morin). Thomas Nacy Jr and Josephine Baker had two children.
