In 1900 Elsie was living with her parents in a rented house at 499 Warren Street, Newark, Essex County, New Jersey. She had not yet entered school in that year.

In 1916, after the death of her father, Elsie was living as a boarder with her mother at 366 South Nineteenth Street, Newark. At that time she was a stenographer employed at at #808, 31 Clinton, Newark.

As she was not listed among the surviving siblings in 1944, when her half-sister Laura died, Elsie was presumably deceased by that date. Unlike most of her siblings she was not buried in the Traudt family section of Woodland Cemetery in Newark, New Jersey.
