MOTHER: Charlotte Ann Smith
FATHER: Punderson Bartow Underhill

HUSBAND: Robert Piper
m. 16 Jun 1842 - Castleton, Rensselaer, New York

CHILDREN:
Martha Eugenia Piper, 1843 –
John Fletcher Piper
Julius Underhill Piper
Robert Willis Piper
Robert Willis "Will" Piper
Harriet Antoinette Piper
Rev. Francis Asbury Piper
(Francis "Frank" changed his name from James.)

NOTE: According to the 1830 and 1840 Censi, it doesn't look like Eliza nor her siblings (except a brother maybe in 1830) were raised by or living with their father, as no females are noted in the household. As her mother died around 1828, it is likely the young children were fostered by other family members or neighbors. Similarly, this happened to Eliza. She died when her daughter Harriet was 4 and son Frank (originally named James) was 1. Harriet went to live with William and Mary Rice Colwell, childless friends of the Piper family back in New York. It is currently unknown who raised Frank/James.
