Her marriage license should have her parents' names on it. You can get a copy of it from the State Archives in Trenton.http://www.nj.gov/state/archives/referenceFees.html
FamilySearch has date of her marriage as 12 August 1882 in Phillipsburgh, Warren Co., NJ
Her death certificate should also have her parents' names, but I did not find an index entry for her death in NJ in 1892. If you know exact date and place, you can order the death certificate too.
